How do I autoformat some Python code to be correctly formatted?

Question

I have some existing code which isn't formatted consistently -- sometimes two spaces are used for indent, sometimes four, and so on. The code itself is correct and well-tested, but the formatting is awful.

Is there a place online where I can simply paste a snippet of Python code and have it be indented/formatted automatically for me? Alternatively, is there an X such that I can do something like X --input=*.py and have it overwrite each file with a formatted version?

Answer 1

Use reindent.py. It should come with the standard distribution of Python, though on Ubuntu you need to install the python2.6-examples package.

You can also find it on the web.

This script attempts to convert any python script to conform with the 4-space standard.

Answer 2

Some editors have an auto-format feature that does this for you. Eclipse is one example (though you would probably have to install a python plug-in).

Have you checked whichever editor you use for such a feature?
