Compare Python Code Online
Use MyTextDiff to compare two files or snippets of Python code and quickly identify what changed in functions, variables, indentation and logic in your script. The comparison is done right in the browser, with nothing to install.
When you select Python for syntax highlighting, the result colors comments (#), strings — including triple-quoted ones (''' or """) — and keywords like def, class, import, lambda and async.
Can I compare .py files directly?
Yes. You can paste the code or upload the .py file directly into the comparison fields.
Does the comparison tool detect indentation differences in Python?
Yes. Since Python indentation is done with spaces, any change in the number of spaces at the start of a line is treated as a difference. If you want to compare the code while ignoring spaces (including indentation), use the "Ignore spaces" option in the settings menu — but keep in mind it removes all spaces on the line, not just indentation, so two lines with different internal spacing will also be considered equal.
