python 获取函数请求来源

import inspect


class do():
    def do_it(self):
        caller = inspect.getframeinfo(inspect.currentframe().f_back)
        print("I'm file:", inspect.getframeinfo(inspect.currentframe()).filename,
              " Function:", inspect.getframeinfo(inspect.currentframe()).function)
        # 输出调用当前函数信息
        print("Call from file:", caller.filename,
              "line no:", caller.lineno,
              "Called from :", caller.function)

    def call_do_something(self):
        do_something()


def do_something():
    caller = inspect.getframeinfo(inspect.currentframe().f_back)
    # 输出当前函数信息
    print("I'm file:", inspect.getframeinfo(inspect.currentframe()).filename,
          " Function:", inspect.getframeinfo(inspect.currentframe()).function)
    # 输出调用当前函数信息
    print("Call from file:", caller.filename,

def method_call():
    do_something()


def class_call(obj):
    obj.do_it()


if __name__ == "__main__":
    method_call()  # 这里是方法 调用方法
    print("-----forasp 分割线---------")
    Obj = do()
    Obj.call_do_something()  # 类 调用 外部方法
    print("------forasp 分割线--------")
    class_call(Obj)  # 外部方法通过类 调用类方法
