Python Language Services

Python provides a number of modules to assist in working with the Python language. These modules support tokenizing, parsing, syntax analysis, bytecode disassembly, and various other facilities.

These modules include:

• parser — Access Python parse trees
  • Creating ST Objects
  • Converting ST Objects
  • Queries on ST Objects
  • Exceptions and Error Handling
  • ST Objects
  • Example: Emulation of compile()
• ast — Abstract Syntax Trees
  • Abstract Grammar
  • Node classes
    • Literals
    • Variables
    • Expressions
      • Subscripting
      • Comprehensions
    • Statements
      • Imports
    • Control flow
    • Function and class definitions
    • Async and await
  • ast Helpers
  • Compiler Flags
