Python Programming Tutorial - 4 - Modules and Functions

[xcvsdxvsx]

"something like absolute value would be really difficult to program if you didnt have a function"

really....

if i<0: i=i*-1

[soho2014]

great teacher. I love these videos.

[xRockDaFunkx]

You really do a fantastic job on these tutorials! You explain, demonstrate then explain each part once more. Now that's a tutor ^.^

[laidman2007]

Am really appreciating these tutorials.

[Gdslayer7]

FIRST!  :P

[FornicateWithRaptors]

@Gdslayer7 That..... wasn't even remotely close to being first. you were over three years late, bro.

[jefsut]

These are fantastic, thanks!

[2yung4grey]

my girl sqrt all the time. i love it.!!!!!!

[iConformist]

"...absolute value would be really difficult to program without a function" uh... if value lt 0 value * -1 else value. haha

[TheOnlyJKid]

@iConformist dude i dont understand one think u just said, but i hope i do in the future :D

[minecast404]

cool tuts!

[MrNeemer]

First

[Ashitaka255]

For the meaning of absolute numbers (for those of us with a poor maths education): An absolute number is what it would be if we disregard it's sign, -3 is 3, 3 is 3 OR how far away it is from zero, -3 is the same distance from 0 and 3 so they both have the same absolute value.. Look on Wikipedia, brilliant explanation.

[AussieRaver1996]

@Ashitaka255 Thanks for the info! =D

[LmfaoReviews]

Wow i had bought a python book for kids and u just taught this better. How can a person thats not even being paid to do this make it easier to learn how to program than someone who is. I don't know, but keep make these videos!

[Apope12341]

@LmfaoReviews thats true i downloaded a book to learn but i didin't understand a thing. i thought the video tutorial is more good to learn those programing languaches

[Xoneize]

well I'm like only 14 years old and HOPEFULLY not too young to learn this.... want to work with computer programs next time =/

[LmfaoReviews]

@Xoneize im 13 and i hope to do the same :)

[TheSturdge]

@Xoneize Stuff like python or Ruby is recommended if your 13/14... wish I'd have known that when I was 14, ended up learning VB.NET instead. I regret that decision

[StarsHero8]

Sorry for like double posting but how to remove numbers/functions from variable

[salabiali]

@StarsHero8 good question ,, hopefully bucky is not too busy to answer your questuion,, lol

[Pvmiguez]

@StarsHero8 Why would you need to remove them? If you want the variable to do something else just assign something else. If you dont want that variable just don't use it. Simple as that, unless I'm wrong.

[StarsHero8]

LOL Extra Crap You are awesome man! You actually talk clearly and explain well! Also funny :P

[channel102030405]

@StarsHero8

i agree

[poet1235680]

he is soooooooooooo funny and good at this.

[steveeliasbelabbas]

@GoglingStuff ye usin imaginary nubers wouldnt it use i 

[v1k1n95]

"Get outta here box."

[steveeliasbelabbas]

y cant i do square root -1 to get i

[GooglingStuff]

@steveeliasbelabbas negative numbers dont have square roots

[52islucky]

look at kahn academy in computer science. also very useful

[takforalt]

This is great. Thanks so much for taking the time to put this up.

[SpeakerFrequer]

I need some help! I know how to import but once I import I want to see the different functions in the module. I know this is dir(math) for example, but then how do I see a description of what each function in the module does? I know there is a way, I have done it before but I am not remembering how.

[SpeakerFrequer]

@SpeakerFrequer nm, figured it out... help('...') does it and help('modules') lists the built in modules... dur... brainfart :p

[xodnoob]

@bunvia click the TAB key.

[bunviva]

How did you get the box to pop up after you did the math.sqrt?

[ehabcharek]

FIRST!!!!!

[gmaster351]

I paused the video to do some practices with the floor function. the very next thing I tried was sqrt function.

[tectful]

You and Khan Academy have changed the way I learn. Thakns!

abs is not difficult to program AT ALL. if x<0; 0-x=retval; return retval

[adjgamer]

And now i know my ABDs XD!

[duskshadow1219]

aww, i used python for like 6 months and on my 2ndary school, they use borland c++ shit. :|

[azazelahh]

abs would be really difficult to program?? how about if a number is less than 0, multiply by -1?

[atulkakrana]

Thanks man...very useful resource. But the problem is some these examples don't work on latest python (v 3.2). Still good work.

[uraniumu242]

@atulkakrana if you use pyscripter it will help you correct it for the lates version. in other words it will suggest what it thinks you mean for the current version. You can also run pyscripter under various versions up to I think 3.1

[ArswawWorldofWarcraf]

@uraniumu242 What is Pyscripter?

[az100eletronics12]

"Extra crap"...Love it!

[GhostXoP]

absolute value

[videomakerforyuou]

First!

[SuperAnand47]

is this same on fedora 14's terminal

[donvitocorleone187]

question bucky........how do u know what is contained in the modules. Is there some where that shows everything u can do for every module

[17171700]

@donvitocorleone187 type help(module) ex. >>help(math) . it displays a man page of the modules

[farfromearth182]

very similar to C++...instead of #include u use import...nice tutorial ;)

[Murphyalex]

Such a charismatic guy :) Makes watching these all the better.

[CrazyShooter199]

I find this easy to masturbate to.

[twentyhead]

thank you!

[skillet748]

How to CLS in python

[smoke489]

"So right now Python is just like looking at it and be like 'Floor ? What the heck are you  talking about, what does that mean ?' "

- LOL

[PoorRichardSaunders]

@smoke489

Sorry I am kind of slow. I just realized that you were quoting another comment and not actually asking yourself.

[TheDarthNefarian]

To find square root without math functions:

print (16**(1/2))

MAKE SURE TO replace 16 with what you want to find the sqrt of. Thumbs up so others see.

[hello12913]

wam bam !!! :D

" In the last the tutorial I was throwing around the world. What?! The world?! I meant the word."

[yjundong]

i love yr tuts.... it's easy to understanding....

[PretendHome]

I'm going to start learning AP Programming in a few days, and i picked Python as my language, so for a head start i started learning before i go to class. Class begins in Tuesday, wish me luck. :D

This videos are really easy to understand by the way, i hope my class is like this. :P

[DigGil1]

@PretendHome though luck for me. My teachers only knew Pascal and BASIC.

[Acceptable76]

@PretendHome So how is it?

[t94j00]

@PretendHome Good luck!

[Desulat0r69]

Program within a program, FUNCTION

[mladenbla]

I like tutorials like this,i know much more now :)

[stopmdot]

thanks buckLy

[zwinky588]

AM i the only one who relizes how USELESS floor is if ur even the stightest bit good at math?

[irishmangiant]

This guy is cool, moreso because he sounds like the cheerleader guy in dodgeball :)

[clab077]

i'm learning more in an hour than in months of school. thanks man.

[chrisrobertskogheim]

i fuckin love your tuts, seems like i can finally learn something <.< :D thanks alot

[blackhat11907]

if you type 'from math import *' you wont have to use math.floor() you can just use floor() :P

[TecchyTutorials]

what the heck is a "abd" i loled at that.

[MUTORIALS]

[intensechap]

Lol, the end was funny..so true though ;)

[owenw97]

Extra Crap!!!

[phoshizzledrizzle]

how did you open the box at 4:29 ??

[kevinhkp]

@phoshizzledrizzle ctrl + shift + space or wait for a while

[intensechap]

@phoshizzledrizzle ctrl+space for me

[hamrwolf]

can you do square roots



[GameNexGenTactics]

Thankyou for these tutorials they have helped me becuase i have always wanted to be able to program in a type of languge such as python and you have helped keep making the videos thumbs up if you aggree

[vinumace]

nice



[Thegoshjosh95]

how do you know all these like abbreviations? like how do you do that box, cuz i wanna learn more than just sqrt and floor :P haha but i love your tutorials man, hella easy to understand :)

[Frequency31]

@Thegoshjosh95 Go to Edit on the tool bar then click Show Completions

what's the meaning of L????

[EvilzElmoz]

You are the best teacher ever! I have watched 4 tutorials without getting a big headache :)

[danieldenfemte]

lol that was stupid, hahaha. i didnt relize i could just type it myself ^^

[danieldenfemte]

can you type math in the python manual to see the owerview of all math functions?

[phroggyy]

"extra crap that's built into python" xD

[klercke13]

@ScottRobot88 1rd? 1rd? it's FIRST!(or 1st) NOT 1rd!

Is anyone else learning this for Blender? :D Yeah? :) Anyone...? Oh :(

[Ajvarxxr]

@spiceuvlife I am learning it for blender =D

holy fuck python made simple by bucky. ty very much sir.

[caberwacky]

Floor... What the heck does that mean? My computer is confused right now...

[TheMario8236]

BEST. TEACHER. EVAR!

[ruchirsharma7]

1234 likes! =)

[s2pidmonkey]

could you assign a variable to a module and function without importing it first?

[phonecpus]

instead of assigning a variable to a function you can specify the function that you want from a module .

for example :

from math import sqrt

with this method you can simply say :

sqrt(81)

[Jesusability]

Which IDE is this guy using?

[joonas2345]

@Jesusability did you mean "IDLE"? if you did then 2.6.1 but you should use 2.7.2

[Jesusability]

@joonas2345 hehe thanks :)

[runekri3]

me: floor(18.7)

Python': floor??!! what the hell is that??

[eaglebaize]

Module = Extra crap that is built into Python. GOT IT! :D Haha Thanks for making these videos!

[TheJackGoode]

getoutofhere! baxx!

[blkbearh2o]

Lmao power abs

[pandelis14]

what is abs(-18)

[kmellos]

@pandelis14 abs stands for absolute (value) and it represents a number's distance from zero on x axis. To do it quickly just remove th minus symbol if it has one. If not, the absolute of a number is itself

[juanfdoroman]

you're the man dude. I'm in a remote area of the world and thanks to you I can learn this. Thanks SO much

[santirosaz]

omg! you are my hero...!

[coolman9999uk]

first!!!! Yes I got the first!!

[sleepersix]

I don't understand why you don't have to import math for pow() but you do for floor()

[ridinghorse123345666]

im making a replacement to husky express called sled crossing with python X3

[Krondelo]

I love programming! And I can't even make much of anything yet.

[OppositionDept]

You are so awesome! :O

[NaMeLeSssFaCeLeSss]

get out of here box!

[pearl2k11]

but wait a minute... wouldnt 18.7 round up to 19 ?XD

[KrisThePolishman]

@pearl2k11

floor round down (cuts decimal off)

[Addv3rsitY]

What if I am trying to import something that does not exist to the program or is not recognized?

[do11arswinner]

dude i hate math, but now.....I THINK I LOVE IT O-O"

[TheJuli1241]

The best teacher!

[MarcusGlent]

Pow! Bizzle Bizzle.

[EvilGenius447]

I'm watching these videos and taking notes. I pay more attention to this than in my actual class.

[LPSlasher]

Lol turn on captions and have a laugh xd

[sirius2012s]

nice tutorial

[jtx8848]

awesome video, thank you!

[liutenghou]

first!



[grizzlybayer]

"a module is pretty much extra crap that is built into python" lol

[abeerashid1]

amazing can't thank u and ur work enough. keep it up

[jaisonangeveettil]

I LOVE YOU

[crmfghtr]

Good stuff, Bam!

[SilentZV2]

1st

[ploglo13]

Awesome tutorials, the only problem is that i use 3,2 not a 2 version so i kinda have to learn a bit bit its no problem, great job

[hotrodzb]

hey bro, i love this tutorial about functions and all, but i have one more question. At one point in the tut you spawned a whole list of functions. How do you get that?

[sailornaruto39]

@hotrodzb from what happened to me, it happens after you use that import command and then try to use a function from the module you imported.

[chiezecuize1]

you are the most effective teacher i hbave ever seen... Bucky youare the man and i really want to know you more...thanks..

[TheIncredibleMass]

BAM!

[key0bb]

"extra crap that's built into python" lol

[MichaelisOnYourtube]

haha, "get outta here box!" 4:34

[x684867]

I love how "modules" are just "extra crap"....somehow I missed that back in '93 when I took CS101...lol.

[psicosisROCKERe1]

thanks! it's descriptive! :))) x

[ServerBoost100]

How do you get that suggestioner box? (I am on Python 2.6.6)

[StrangerEight]

@ServerBoost100 I was wondering the same thing! Please let me know if you find out..

[synclicious]

lol abd

[ServerBoost100]

@synclicious adb is actually a Program. It is "Android Device Bridge".

[cotorrafina]

now I can use python like a calculator.

all math is done with this

[Zeiterius]

[kvg784]

Very nice series. Looking forward to watching the rest of these.

[2acox]

get outa here box!

lol

[newdreamscreations]

Python rocks! I am going to start using Python

[masterchief9064]

how do you bring up that box that shows you all the functions that you can do?

[Killtacboy]

Brilliant tutorials; I'm having fun and learning! Thought those two were supposed to conflict.

>>> Fun + Learning = ( x/0 )

ERROR Cannot divide by 0

[fatihli21]

thks , great tut, better than profs ;)

[firetryer]

Pfft! Who Needs Window's Built In Calculator When You Have Python To Do Your Homework!

:P

[luisellys]

there are15 stupids... too dumbs to understand this tutorial!

[xyzdorky66]

Omg I love python, fuck c++

[INTEL64GAMER]

@xyzdorky66 lol I was thinking exactly the opposite

[xyzdorky66]

@INTEL64GAMER im lazy and decided i didnt want to finish c++, i not going to be a serious programmer

i wana work on cars for a career

[itachisxeyes]

@xyzdorky66 I have to say I love C after all I got started programming on Unix, but C++ has the most awkward implementation of Object Oriented Programming ever, XP

[xyzdorky66]

@itachisxeyes i kinda started on c but learned more c++ and it was a weird transition:P

c++ has alot of unnecessary code i have to type that python nor c doesnt. im prolly gonna keep using c ++ but python is really nice=]

[pozionmynd]

i thought the pow functiuon was part of the math modual??

If this the case why can u use the pow function without importing math??

love ya shit mate keep it up :)

[Zeldakitteh]

@pozionmynd It is one of the built in functions.

docs.python.org/library/functi­ons.html

[shadikixcv]

good teacher

[chaoswolf715]

When he said pow i shouted "POW!"
