Question

Sometimes python 2.5.4. does not automatically indent, so I indent 4 spaces and I always get an error. I am stuck on the third lecture! How do I fix this?

Answer 1

for example after a while statement and two indented lines below it, if will not go back to the margin.

Answer 2

What editor are you using?

Answer 3

I think some editors require consistency between using tabs and spaces..You can't combine both in the same script..
I use Sublime Text, and no issues with the Python compiler.

Answer 4

If you are using vim, put this into your .vimrc and everything will work flawlessly:

" 1 tab = 4 spaces, auto indenting
filetype indent plugin on
set tabstop=8
set expandtab
set shiftwidth=4
set softtabstop=4

Answer 5

Although visually the same, four spaces are not the same as one tab. Blocks of code (the indented lines) have to use the same indentation throughout that block. IDLE has a problem with this, so it's not one that I use.

Answer 6

I do not understand why the professor of the course can use python Idle with no problems, and I can't!

Answer 7

Are you typing a colon after ifs and loops?

if <condition>: \(\leftarrow\) it is that : that triggers the indent.
