How can I check the syntax of Python code in Emacs without actually executing it?

Question

Python\'s IDLE has \'Check Module\' (Alt-X) to check the syntax which can be called without needing to run the code. Is there an equivalent way to do this in Emacs instead of ru

Answer 1

Or from emacs (or vim) you could run python -c 'import x' where x is the name of your file minus the .py extension.

Answer 2

You can use Pyflakes together with Flymake in order to get instant notification when your python code is valid (and avoids a few common pitfalls as well).

Answer 3

You can use pylint for such things and there seems to be a way to integrate it into emacs, but I've never done the latter b/c I'm a vim user.

Answer 4

python -m py_compile script.py

Answer 5

You can use pylint, pychecker, pyflakes etc. from Emacs' compile command (M-x compile).

Hint: bind a key (say, F5) to recompile.
