1//! This crate provides Python language support for the [tree-sitter][] parsing library.2//!3//! Typically, you will use the [language][language func] function to add this language to a4//! tree-sitter [Parser][], and then use the parser to parse some code:5//!6//! ```7//! let code = r#"8//!     def double(x):9//!         return x * 210//! "#;11//! let mut parser = tree_sitter::Parser::new();12//! parser.set_language(&tree_sitter_python::language()).expect("Error loading Python grammar");13//! let tree = parser.parse(code, None).unwrap();14//! assert!(!tree.root_node().has_error());15//! ```16//!17//!
