Parso is a Python parser that supports error recovery and
round-trip parsing for different Python versions (in multiple Python
versions). Parso is also able to list multiple syntax errors in your
python file.

Parso has been battle-tested by jedi. It was pulled out of jedi to be
useful for other projects as well.

Parso consists of a small API to parse Python and analyse the syntax
tree.
