def visit_import(self, node: _ast.Import):

# 需要导入模块: import _ast [as 别名]
# 或者: from _ast import Import [as 别名]
def __init__(self, name, source):
# A dot should only appear in the name when it is a submodule import
assert '.' in name and (not source or isinstance(source, ast.Import))

def parse_source_file(file_name):
"""
Parses the AST of Python file for lines containing
references to the argparse module.
returns the collection of ast objects found.
Example client code:
1. parser = ArgumentParser(desc="My help Message")
2. parser.add_argument('filename', help="Name of the file to load")
3. parser.add_argument('-f', '--format', help='Format of output \nOptions: ['md', 'html']
4. args = parser.parse_args()
Variables:
* nodes Primary syntax tree object
* argparse_assignments The assignment of the ArgumentParser (line 1 in example code)
* add_arg_assignments Calls to add_argument() (lines 2-3 in example code)
* parser_var_name The instance variable of the ArgumentParser (line 1 in example code)
* ast_source The curated collection of all parser related nodes in the client code
