Python Parser
Parse Python source into a searchable structural outline containing imports, classes, functions, decorators, parameters, and line numbers. The browser-based parser does not execute code and can export its findings as JSON.

What this developer tool does
It performs indentation-aware static extraction of common Python declarations. The output is useful for code navigation, documentation, and lightweight dependency review.
Mask strings and comments → scan declarations → read indentation → associate decorators → extract signatures → serialize structure.
Dynamic declarations, unusual multiline signatures, and metaprogramming may not be fully represented.
Example
Input
class Circle:
def area(self, radius):
return radius ** 2Output
Circle area(self, radius)
Tips for better output
- Use JSON output for downstream processing.
- Use Outline for a compact human-readable summary.
- Validate highly dynamic code with Python ast tooling.
FAQ
How do I extract all functions from a Python file?
Enable Include functions and run the parser to list function names, signatures, and line numbers.
How can I list Python classes and methods online?
Enable classes and functions; nested methods appear with their indentation level.
How do I generate a Python code outline?
Choose Text Outline and parse the source.
Can I export parsed Python structure as JSON?
Yes. Choose JSON Structure and download the result.
How do I find imports and decorators in Python code?
Keep imports and decorators enabled; they are extracted into separate fields.
