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
