How do I compile a Python script without running it? I just want to check the script for syntax errors. I was hoping for a simple command line switch, but I didn't see anything in python --help. I'd like an answer for both Python 2 and Python 3.

Python Solutions

Solution 1 - Python

python -m py_compile script.py

Solution 2 - Python

http://docs.python.org/library/py_compile.html">py_compile — Compile Python source files

import py_compile
py_compile.compile('my_script.py')

Solution 3 - Python

You can use pylint to find syntax errors as well as more subtle errors, such as accessing undefined variables in some rarely-used conditional branch.

Solution 4 - Python

One way is to do something like this (for test.py):

python -c "__import__('compiler').parse(open('test.py').read())"

This works for Python 2.x.
