Review Python code online
Get a Python-aware review: PEP8 readability, exception handling, mutable defaults, and the subtle gotchas that pass tests but break in production.
Python lets you write code that reads as correct and runs fine on the happy path while hiding traps: mutable default arguments, swallowed exceptions, late-binding closures in loops, and silent type coercions.
The Code Review tool reads your Python and flags these idiomatic pitfalls along with general logic issues, then explains the fix in Python terms you can apply immediately.
It is handy for learning the language’s sharp edges, cleaning up a script before sharing, or sanity-checking generated code you do not fully trust.

Frequently asked questions
Does it know Python idioms? +
Yes. It flags Python-specific pitfalls like mutable defaults, bare excepts, and loop-closure bugs alongside general issues.
Can I review generated Python code with it? +
That is a great use. Paste AI-generated code to verify it before you run it.
Does it check style too? +
It notes readability and PEP8-style concerns, but prioritizes correctness and safety over pure formatting.
