Beginner question about indents
I like Python, but find the correct indentations a little cumbersome to count. Is there a visible character that counts as an indentation?

I'm a little confused by the question. Do you mean like a character(s) that would do the same thing as pressing tab? That would be '\t'.

i am not sure what he means either. but i think he means an editor showing the tabs...most editors have options to show you the tabs like this: (see attached image) ...althought i don't know if that's what you want.

Why are you having to count anything?

What editor are you using? If it is something like Notepad then get yourself a proper programmers' editor.
The important thing about Python indentation is that it all the lines in a block line up with each other - the actual number of spaces does not matter. If all the code in a function is on one screen and you are using a fixed width font then you can tell this just by eye. If you are not using a fixed width font then change it - programming in a proportional font is painful. If your functions are bigger than a screen then they are too big anyway, and should be refactored into smaller functions.
A decent editor will help you in many ways, e.g.
* letting you set a tab size and automatically converting tabs into the right number of spaces (4 spaces per tab is the defacto Python standard).
* showing you guide lines when you indent a block
* having a mode where invisible characters become visible (e.g. spaces are converted to a faint dot)
There are lots of free editors that can do some or all of the above - Jedit, SPE, emacs, vim, etc. For a comprehensive roundup of Python-aware editors see here.

If your looking for an alternative way to indent your code then the answer is no. The only characters you can use to indent your Python code (unless you want to run your code though a custom built preprocessor) are tabs and spaces, which won't be visible unless your editor supports this as the guys have said.

or here for IDEs...

Thanks for all your ideas, sorry about not being clear enough! I am actually using the Crimson Editor, so this example solves what I wanted. I just wanted the tabs/spaces to show up at times, since I gotten errors when the exact amount of spaces didn't match!

Thanks a lot coach! I got the PythonWin editor and like it already. It has a whitespace option with the faint little dots, perfect! Problem solved!
