How To Install python3-parso on Debian 10
Introduction
In this tutorial we learn how to install python3-parso on Debian 10.
What is python3-parso
python3-parso is:
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.
A simple example:
import parso module = parso.parse(‘hello + 1’, version=“3.6”) expr = module.children[0] expr PythonNode(arith_expr, [<Name: hello@1,0>, <Operator: +>, <Number: 1>]) print(expr.get_code()) hello + 1 name = expr.children[0] name <Name: hello@1,0> name.end_pos (1, 5) expr.end_pos (1, 9)
To list multiple issues:
grammar = parso.load_grammar() module = grammar.parse(‘foo +\nbar\ncontinue’) error1, error2 = grammar.iter_errors(module) error1.message ‘SyntaxError: invalid syntax’ error2.message “SyntaxError: ‘continue’ not properly in loop”
