pydiff diffs Python code at the bytecode level. This is useful for checking for changes to the actual code structure while ignoring formatting changes.
From pip:
$ pip install --upgrade pydifffoo.py:
import os, sys
def main():
x = len(sys.argv) + 100
y = x+77
print(y)bar.py:
import os
import sys
def main():
x = len(sys.argv) + 101
y = x + 77
print(y)$ pydiff foo.py bar.py:
--- foo.py
