下面是一个使用AST模块实现批量加注释的示例代码: importastdefadd_comment_to_code(filename,comment):withopen(filename,'r')asfile:code=file.read()tree=ast.parse(code)comments=ast.get_docstring(tree)ifcommentsisNone:ast.fix_missing_locations(tree)tree.body.insert(0,ast.Expr(ast.Str(comment)))a...
asname) withitem = (expr context_expr, expr? optional_vars) type_ignore = TypeIgnore(int lineno, string tag) } 节点类 class ast.AST 这是所有 AST 节点类的基类。实际上,这些节点类派生自 Parser/Python.asdl 文件,其中定义的语法树示例 如下。它们在 C 语言模块 _ast 中定义,并被导出至 ast ...
Unfortunately,typed-astdoesn't provide any means to go from AST back to source code with type comments. This is why moduletyped-astunparse(i.e. this one) was created: to provide unparser for AST defined intyped-ast. Example of roundtrip from code through AST to code: ...
所以我们可以通过constantViolations、referenced、references、referencePaths多个参数来判断变量是否可以被删除,AST 处理代码如下: const parser = require("@babel/parser"); const generate = require("@babel/generator").default const traverse = require("@babel/traverse").default const code = ` const a = 1...
ast.parse(source, filename='<unknown>', mode='exec', *, type_comments=False, feature_version=None) 把源码解析为AST节点。和 compile(source, filename, mode,ast.PyCF_ONLY_AST) 等价。 If type_comments=True is given, the parser is modified to check and return type comments as specified by...
除了手动编写正则表达式,我们还可以使用Python工具库来实现一键取消注释的功能。下面我们将使用ast库来实现: importastdefremove_comments(file_path):withopen(file_path,'r')asfile:tree=ast.parse(file.read(),filename=file_path)fornodeinast.walk(tree):ifisinstance(node,ast.Expr)andisinstance(node.value,...
Typed AST typed_astis a Python 3 package that provides a Python 2.7 and Python 3 parser similar to the standardastlibrary. Unlikeastup to Python 3.7, the parsers intyped_astincludePEP 484type comments and are independent of the version of Python under which they are run. Thetyped_astparser...
