将返回值添加到python中的列表？

Question

When I print this I get:

FuncA
FuncB
FuncC 

When really what I want is:

['FuncA', 'FuncB', 'FuncC'] 

How would I be able to iterate through my returned values and add them to the list?

Rather than manually look for text (which can easily lead to false positives), use the ast module to build an abstract syntax tree, then extract function names with that:

import ast

functions = []

with open( 'codefile.py', 'r') as file:
    tree = ast.parse(file.read(), 'codefile.py')
    for node in ast.walk(tree):
        if isinstance(node, ast.FunctionDef):
            functions.append(node.name)

print(functions)

This finds all function objects anywhere in the source code, just like your search for def text would have. Except this skips commented out code or the word def in a string literal, for instance.
