打印函数名

从内部取

def a():
    print("hello")
print(a.__name__)
print(a.__getattribute__('__name__'))
print(getattr(a,'__name__'))

通过sys模块

import sys
def a():
    print(sys._getframe().f_code.co_name) # f_code和co_name可以参考python源码解析的pyc生成和命名空间章节
a()

通过inspect模块

import inspect
def get_current_function_name():
    return inspect.stack()[1][3]

class MyClass:
    def function_one(self):
        print("%s.%s invoked" % (self.__class__.__name__, get_current_function_name()))

if __name__ == "__main__":
    myclass = MyClass()
    myclass.function_one()
