Python Lists

[BroJoHey]

which program do you use for drawing!!!

[hehongfei1009]

millions of thanks.

[Nameless1324]

you are a genius, I don't know whether I'm intelligent or you make this mind bogglingly easy to understand but I get it, you make it intuitive and more importantly interesting

well done

[DarklightALBANIA]

You should start doing html ,or visual basic

[xXTheRush905Xx]

@DarklightALBANIA Never Visual Basic, no one uses it.

[Bakugantsuvai1]

@xXTheRush905Xx except the professionals or crazy people who want to create insane viruses.

Thanks Sir

[desipimp299]

hi, your computer programming videos are very well explained. can you please do more of them?

[furssher]

MORE PYTHON??? NOOO

[dedly13]

holy shit, i used this guy for my gcse's and a levels for maths, science and some other stuff and now hes doing programming, wowowowowowowowowowow. you are one of the best peeps on utube

[PiratWeber]

i'm impressed how good you can write with your mouse. really.

[ghj6363]

@PiratWeber he is not using mouse but interactive board!

[snodgers]

Type python 3 in google, download the appropriate package

[latetilla0205]

Where can I get the software?

[MrLegendman3]

@latetilla0205 He is using python 2.7 google it

[paulceltics]

thanks

[gmandog6]

is there a negative 1. Just wondering.

Thanks for the videos but i have noticed that your explanations do not go in-depth. Please, the more the better.

[eragon4125]

@gmandog6 i think they are just light explanations of what it is and the man does most of the videos in the academy so he has to know alot

there are 100's of videos

Anyone looking for practice in Python should check out a website called "codingbat"

Lots of great problems on there, for Python and Java.

[fcdoth]

This is a great primer to python lists.

One thing you could do in your python interpreter though, and since you mention memory references, would be using the "is" python operator to actually prove that one list is actually a reference to some other list:

>>> a = range(10)

>>> b = a

>>> c = a[:]

>>> b is a

True

>>> c is a

False

>>>

I have Question Khan, please answer:

How the Hell do you know everything from a wide range of science ? I mean, you know math, programming, chemy, physics etc.

:D

Tanx for your videos ^^

[Ferrus91]

@eliot0x103 Yeah, I know that, what I was wondering was whether there is anything in the library which produces a textbox with a list of entry boxes in which individual components of the vector can be entered.

[LiamGoodacre]

Good introduction to lists, except:

0th element would be at index -1;

1st element would be at index 0;

nth element would be at index n-1;

[0 -> 1st, 1 -> 2nd, n-1 -> nth]

[Rozenkrantzz]

Thank you soo much. Iv'e been trying for weeks to teach myself python

[IEOA]

@Rozenkrantzz

You can try watching TheNewBoston's Python programming tutorials (just search it on YouTube). They help a lot!

[DehXable]

Sal you should consider doing problems from Project Euler. You can Google it. It's a site dedicated to math/CS problems of varying difficulty. They're arranged by how many have solved them. Maybe you could do some of the harder ones in Python. Once you reach a certain level in CS the best way to progress is just working problems.

[slsl0]

@DehXable Great idea

[Ferrus91]

Is it possible to use the input function to get the user to enter numbers directly into it?

[eliot0x103]

@Ferrus91 Obviously: a.append( input( "input something" ) )

[textdriven]

I just want to say a big thank you for doing this. I've been wanting to learn proper programming for a while now and I have always been told to start with Python. I've trying a few free ebooks but haven't been able to stick with them. Your videos make it very easy and clear. Thank you.

[asdfqwerty2000]

@textdriven Good luck with it!
