Python Programming Tutorial - 8 - Raw Input

[rafaelsalinas58]

I want this video on my Doraemon phone.

[t94j00]

I bet your name is Greg. It says where the file is stored "C:\Users\Greg\Buckey.py

LOL @ YOUR LIES!!!!

[Jacksonisking1]

anyone know why when i deleted python3.2 to make sure my programs always ran in 2.7, i can no longer open my python files and when it gives me the list to choose from and i click on python or pythonw in the python 2.7 folder it doesnt load or show up on recomended programs or other programs? i can no longer click edit in idle either. please help!!!

[X0wnageX1]

@Jacksonisking1 did you press f5 to open it?

[cboulos97]

IDLE crashes whenever I open a new window. (I am on mac)

[Geordan271]

@cboulos97 yea, i dont know why it does that but i did it to me so i switched to one of my family members PC..

[cboulos97]

@Geordan271 Re-download it, but click the 32-bit I think.

[fidolimp]

@cboulos97 Get a PC.

[Culinax]

raw_input(..) became input(..)

input(..) became eval(input(..)) but try not to use this one because it can run code (big security risk)

Use int(input(..)) for numbers

[twinsofliberty]

Can you use the raw_input function for intergers?

[The419Clan]

can you make a libary to store a bunch of passwords in it and use it for a log in?

[rednut416]

wow i put toby=raw_input("enter name: ")

print toby*10 and it wrote toby out 10 times insane

[ukki747]

x = raw_input("type your name here: ")

if x= "ukki747": print"welcome " +x

else: print"go away"

I want to have this program print:"welcome ukki747 when I input my name

and otherwise print:"go away.

but it gives me an error on the second line, can somebody help me?

[Nijokaz]

@ukki747 are you for real??



[ukki747]

@Nijokaz yeah, but I figured it out, thx

[bjebn]

Whats the difference between input and sys.argv function? they both require user input ?

[farazhashmi9000]

Thanks Sir Bucky

[thbeserk]

is your real name greg cuz i was looking at the top of the screen and it said something about greg

[disnukka79]

6 and 7 are the same video

[Lazaruzerick]

@disnukka79 the 6th vi is the introduction of the strings and the 7th one is more about the strings, they aren't the same :D

[xoDevilBabyox]

5 people mistaked the "dislike" for "THIS I LIKE"

[JT10831]

@xoDevilBabyox that's so old. attention seeker.

[daredevilpwn]

Just wondering. What is the point of using input when its just numbers when you can just do raw_input which can do numbers and strings?

[VselwynV]

@daredevilpwn If the program treats it as a string and not a number, it can't calculate with it.

Because "I am just a computer so I don't understand" "Letters and numbers, that is not math, not english that's not nothing".!!! :P

[daredevilpwn]

@VselwynV Alright thank you for the clarification

[curryeater259]

is it okay if we just replace raw_input with input? Is there anything you can do with input that you cannot do with raw_input?

[dnryuuzaki54]

Can you convert an INT into a STR. I need my inputs to be numbers so that I can do sums with them but I cant then print them out with a string.

[doanhqdo]

@dnryuuzaki54

yes you can. For example

a=5

b= str(a) #converts the value of a into a string

c= int(b) # converts the string of b into an integer

a + c

>>> 10 # the sum of a and c is 10

[EAGangstad]

And raw_input() is input()

[EAGangstad]

Those of you with Python 3-- Print is a function. . . print("Print is a function!!")

[IrishCowboy87]

i was under the impression that with the new programs, you can still run raw_input it just does the exact same thing as input

[murtaza3113]

hey bucky u r0ckzzzzzzzzzz.. liked ur every tutorials very much.. very inf0rmative.. u r teaching very well.. :)

[ecvsio]

BAM!!! :D

[iReVoDesigns]

In python 3.2 it would be

buck = input("Enter name: ")

print (buck)

[penguin4four]

thats cool. What i was doing was

str(input(Enter name: ))

[ModdingNation1]

Thanks so much for this video series, its so helpful

[EvilGenius447]

5 people thought python was just a snake.

[mcaprasad3]

Great videos and very helpfull for me i just started to roll the ball.... thank you..

note: function raw_input() in not wrking in python version 3.2

[mcaprasad3]

note: function raw_input() in not wrking in python version 3.2

[crashowerride]

raw_input() in 2.6 is input() in 3.x

input() in 2.6 can be done by eval(input()) in 3.x

THUMBS UP TO KEEP IT ALIVE!!

[Richificationism]

its great, in 8 videos he has turned what was to me an insolvable program into something i can use. thankyou

[hntommylam]

thanks 

[MrFlyingLeaf]

Cool man. I do love the tutorials. Damn the courses I had in the univ

[Andys12169]

Ahh got it now, had commented on that earlier.

[CSryoh]

difference between input and raw_input:

[anizzle54]

Thanks so much for your tutorials. I made my first module ( a chat module) from your other tutorials. Thanks so much!

[basicxml]

buck=rocky rock rocky hes awesome

[85rajnish]

just now start your tutorial i like it let me go through all than ill get back to u

[9KindsOfCrazy]

Just a note everybody, in Python 3 raw_input isn't recognized as a function and will return as an error. However, input() now works for all the things it didn't work for in Python 2.6. Please thumbs up this comment so everyone else can see it and help raise awareness on this update.

[AstroCamo]

@9KindsOfCrazy Switch to Python 2.7

[9KindsOfCrazy]

@AstroCamo I'm really thinking about it. I know some of the things they changed were to make it more efficient in the future, but really? Compatibility is horrible. I can't even get Tkinter to work, there goes GUI programming.

[TubeFreakification]

@AstroCamo Good advice

[phroggyy]

@9KindsOfCrazy wrong: raw_input is indeed recognized when the code is run, I can prove it... At least in 3.2

Btw, for all to see: you can also type int(raw_input('text goes here')) if you want an integer input, as raw input ALWAYS make it a string

[Colstonewall]

@9KindsOfCrazy Thanks for this!!! Very helpful.

[MilitiaGFX]

Man, I just wanna say thanks! because you have put much time in these tutorials and i guess it was a whole lot of work. I love it how in the beginning you start with loose ends and by the time you go further everything adds up and works together :D and I love your way of explaining, man again thanks! I can't say that enough, I subscribed, but I wish i could subscribe like a 1000 times ;p

[trr12]

i love it when he says "bam!". I'll say that everytime I run a programme, it adds a thrill to it.....

[jillybooty]

This doesn't apply for python 3 does it?

[braunmarci]

No matter what video I watch, YouTube wants me to date Chinase women.

BTW cool tutorials, thanks a lot!

[andregiestas]

When I was programming at DELPHI I could use the ISNUMERIC() function combined with DO UNTIL LOOP.... But using PYTHON I really don't know how to easily create a INPUT and be really sure that this input is really gonna be a number...

[andregiestas]

I could solve it using GAMBI PATTERN DESING (LOL, TRY ... EXCEPT....)

It is not the best way but it is the only I know from other languages...

[MrMicsau]

I'm coding now!!! with less then a day experience in programming.

[tttlycoolxtreme7dude]

dude u didnt tell us aoubt raw input

[rohit91]

Subtitles and this video rocks. I re-watched it with them on and got 100x better results.

[123IOWNALL321]

I'd rather not use IDLE to run my program. Is there any way to stop the command prompt from automatically closing once the program is finished running?

[jdwolfears]

@123IOWNALL321 Tutorial 5 - How to Save Your Program. Watch the end of it.

[itachisxeyes]

@123IOWNALL321

before the return statement at the end of your program, place an input statement, the prompt will wait for a key press and once you are done you can press any key to close.

its barbaric but simple and will be good enough for now.

real GUI programs are basically one big loop and once the 'X' is clicked it make a break statement from the loop. but the input statement will be good enough for when you are just learning or are doing something simple (^_^)

[123IOWNALL321]

@itachisxeyes

Thanks...but I figured it out like a month ago lol. It's still useful to this day though :)

[itachisxeyes]

@123IOWNALL321 yeah...after i posed, i looked up and saw someone had already answered your question. (<_<)

[iopabc123789]

i made a little game using python where theres this person you get to name asks you a bunch of questions and stuff and i noticed how raw input worked better in some cases

[hoangchi100]

done and done. subscribed!thanks bucky

[bboybram]

If your following in Python 3.x should you just skip this video since there is only input()

B.T.W. ^^ that ^^ is an question which I would like to be answererd

[masterassassin1]

Now they are both input, because of the newer version. At least I think that's how it is.

[NorwayHack]

@masterassassin1 Correct

[tomek123kotek]

yay i fixed my addition program

[ffffgen]

Thanks po

[ncdave4life]

In Python 3, raw_input() is now called input(), and the old version 2 input() function is unavailable. If you want the old input() function, use eval(input()) instead.

I.e., if your old version 2 Python program said:

n = raw_input("Enter your name: ")

x = input("Enter expression: ")

then your new version 3 Python program would say:

n = input("Enter your name: ")

x = eval(input("Enter expression: ")

[lompocus]

input() supercedes raw_input() for python 3.

[101abob]

how can i make my .py files into a .exe

[Usumgallu]

@101abob I have used py2exe, you can find it by Googling. Only downside is that even a small program will use several megs of disk space, as all the libraries must be included.

I wrote a program (as my thesis in computational linguistics) that analyzes babylonian finite verbs. The source code, lexicon and grammar files were around 250kb in total, but the compiled program is around 5 megs.

Well, not a big problem unless you look for elegancy.

[SubUrbanHunter]

reminds of BASIC when I was a young 11 year old in the 70's, I learned BASIC.

BASIC had a command line like that which is separate from the line numbers. You could run commands in the interpreter like that. Python reminds me a lot of that. The good ol' BASIC.

[ejram3]

THAAAAAAAAAAAAAAAAAANK U BRO FOR THIS Gr8 Tutorials  <33

[leoz1992]

"Você é o cara", thanks so much!

[coladomestre]

i dont really get the difference between input and raw_input...

it's the only thing i didnt understand so far...or one of the few...

[picknpac]

so again no raw_input in python 3 or wat??? again its showing me errors

[scorpion990]

@picknpac

input() in python 3 = raw_input() in previous versions.

[ChewalierAnsatsusha]

Btw, is ur name Greg? :p

Awesome.

[ILIKETOCRY9]

hey, you do great tutorials if you keep doing great tutorials i will sub,rate 5 and comment like what i'm going to do with this one

[GriffinnoFamily]

a=1

b=raw_input("enter max")

while a<=b: print a*a, a=a+1

why this didn't work ????

the answer is there is a difference between 'raw_input()' & 'input()'

thank you man, u shaved my hrs

[SuperiorPancake]

in python 3.xx just use input() it works

[SkimpyDoughnut]

wouldnt you have to use

int(input("Enter max "))?

[SuperiorPancake]

well it worked for me but maybe that works to.

[superpredator78]

Here is a brain teaser. Since raw_input() will accept integers and strings. If you are using raw_input how do you know if the user typed integers? Since they have been converted with no error checking. :)

[minime78]

keep up the good work!! Very helpful for noobs like me!

[Lyerae]

@ss11311086

Wow, that was clever! How long did it take you to come up with that one??

Did you mommy have to help you?

[ss11311086]

welcome everyone, I'm fucky!

[MsTweety76]

thanks bucky :) your videos are the only ones that i truly really understood :) your 'no bull' way of teaching is one of a kind. i hope you can also do some django tutorials someday. looking forward to the other stuff that you will be producing in the future...

[theMastrgamr]

was this function changed or removed in python 3?

[amora101]

ty for the vids :)

[Kraized]

I think he had Version 25.something

[bowendude1234]

what version do you have?

[lfroggyl]

input() returns an integer... so if he writes a number. hes good. if he writes letters it fails.

raw_input returns a string... so if he writes a number. hes good. if he writes letters hes good. because those are string..

idk if bucky said but numbers can be string.

'16' is a string

'buck' is a string

'this is a string' is a string

18 is an integer.

'bucky' is not an integer

[IPlayInBeastMode]

You are wrong. input() assumes that whatever is returned is a valid function. raw_input does not.

That is why if you type...

input()

and a user types...

my name is jon

It will give you an error saying "my name is jon" is not a valid function. Whereas if you did the same thing with RAW_input, it would not.

Raw_input basically converts the information into a string.

[rubikscube10]

one question: bucky, you say input is for numbers and raw _input is for alphbets right? so if u say x = raw_input("write something u idiot") and tht idiot writes a number , will it say error? now what about this one: x = input("write something: ") print x + ("is something") what will happen if he writes an alphabet? error? what will happen if he writes a number? error?

[izrafel1989]

rubikscube10

if you write a numer in raw_input...that number become STR, and you cant operate it with other numbers,

[foad62]

tanx a lot

[1000101er]

input() treats whatever the user enters as python code.

If they put their response in parenthesis it'll return a string. If the user enters 1+ 2**2 it'll return 5.

[r3sp3c791]

lol thanks, I was having a calculator code and i was wondering what is wrong with it because it was working fine untill I decided to put a welcome message for the user and it was like

UserName = input('Hello stranger, what is your name?')

print 'Well, hello now ' UserName

[SiGhast]

Try this instead:

x = raw_input("Hello stranger, what is your name? ")

print "Well, hello now, " + x

That should work fine. Chances are you've already figured it out, though.

[SiGhast]

...Blah, dude. Nevermind.

I hadn't watched the video and I didn't read your full comment as I wrote that.

Now I know what you mean.

*facepalm*

Sorry.

[HordeAreMyFatCousins]

I dont see why python is so popular, its like autoit.

[Edmontonia]

Wow, I just crashed the Python program xD

[papano12]

What is the difference between using the

input ("Hello")  and the

print ("Hello")

[MuppitFood]

If you used print, it would only display hello.

If you used input("Hello") then it would display Hello and ask for the user to type something in.

[salehenShovonRahman]

input is a function that not only outputs a string value, but it also retrieves a number input as well, where as print is only meant to output strings.

[sugatmassey]

input is requesting info from the user. output is printing what was input.

[MakeItRayNee]

thanks man i want to make a game ive been watching the tutorials up to here ill check the rest later peace

[arinlares]

I'm bouncing between Ruby and Python. Thanks for these tutorials, they're ordered like Python's documentation, but more entertaining (hypertext is boring :P).

[Scottk95]

hmmm... ruby ive never heard of that. i think you shoukd use python because its more well known and is a realy good scripting/programming programme for beginners.

[fergus247]

Does anyone know of a webpage that has a list of all the functions possible along with a short description?

Like raw_input, input and so on and so on

thanks

[CrazyMonkey124]

raw_input isnt a command <,<

[AwesomeTown21]

consider me subscribed, bucky

thanks for all the tutorials. impossible to find good ones on the net.

[ankurvasudeva]

CAN YOU PLEASE DO THIS FOR ME !!!!!!!!! THANK YOU

A function called wordList that is called with the name of a .GLOSS file. The utility loads this file into memory as a list of strings. It then searches through the file string by string. Whenever it finds a string beginning “<CONCEPT>”, it displays all text between the <CONCEPT> and <\CONCEPT> tags. In this way, we obtain a display of the terms being defined in this particular glossary.

[ashtonka]

i dont get it where do i type the raw_input ??

i nevre got told that on the 7th video

[wimawa]

If you have python 3 or above, raw_input was removed.

[huntardrape]

thank you.. I am going to use this to make a encryptor/decryptor with this : )... and btw I never noticed u played wow : ) wats ur server/char

; o

[zamliman]

thanks man

[ogglesnorg]

Its best to use raw_input, unless you have a good reason to use regular input. Otherwise, you are trusting the user not to insert python commands.

[letmekilluplz]

My underscorers arent showing up

any help?
