can someone kindly correct me if i am wrong about this quote "As the program contains multiple lines of code, you should create it as a separate file and run it." does that mean that if my code gets bigger it is advisable to create less line of codes but many files?

Isn't this just a reoccurring function called from within itself until a particular set of conditions are met? I don't know it just seems like shorthand to me. Like a do-while loop. I am sure it could be used for more than just factorials.

I've updated it from Filezilla obviously but it just shows a little jpg logo and doesn't display my pic. What am I doing wrong?

The basic difference between Id and class it that, an ID can be applied to only single type of elements no matter how many times you apply or how many ids you create but in slight edge class is same as id but can be applied to different types of elements Am I Right?

Hey there, I don't know why, but when I import tkinter on IDLE like this: from tkinter import * And I say: window = Tk() Even known I use python 3.2.5, which should be able to use Tkinter, the python shell raises a ValueError that says that Tk() is not defined. I am very sure I use python 3.2.5 and tutorials from the Python Foundation say that is what I have to do. But it still doesn't work. Does anyone have an idea of how to solve this problem? Thank you!
