确定Python模块中是否有可用的函数

import inspect

def check_module_functions(module):
    functions = []
    for name, obj in inspect.getmembers(module):
        if inspect.isfunction(obj):
            functions.append(name)
    return functions

# 示例：检查os模块中是否有可用的函数
import os

functions = check_module_functions(os)
if functions:
    print("os模块中有以下函数：")
    for function in functions:
        print(function)
else:
    print("os模块中没有可用的函数")
