Python 語言服務¶
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.
這些模組包括:
ast
--- 抽象語法樹 (Abstract Syntax Trees)- 抽象文法 (Abstract Grammar)
- 節點 (Node) 類別
AST
- 根節點
- 文本 (Literals)
- 變數
- 運算式
- 陳述式
- 流程控制
- 模式匹配 (pattern matching)
- 型別參數 (type parameters)
- 函式和類別定義
- async 和 await
ast
輔助程式- 編譯器旗標
- 命令列用法
symtable
--- 存取編譯器的符號表token
--- 與 Python 剖析樹一起使用的常數tok_name
