str(str(inspect.currentframe())).split(' ')[-1][:-1]

这是一个经得起考验的方法。

将@CamHart和@Yuval的建议与@RoshOxymoron接受的答案结合起来，可以避免:

_hidden和潜在弃用的方法 在堆栈中建立索引(可以在未来的python中重新排序)

所以我认为这对未来的python版本(在2.7.3和3.3.2测试)很有帮助:

from __future__ import print_function
import inspect

def bar():
    print("my name is '{}'".format(inspect.currentframe().f_code.co_name))

更新:在3.7.10,3.8.10和3.9.5测试

import inspect

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

def whosdaddy():
    return inspect.stack()[2][3]

def foo():
    print "hello, I'm %s, daddy is %s" % (whoami(), whosdaddy())
    bar()

def bar():
    print "hello, I'm %s, daddy is %s" % (whoami(), whosdaddy())

foo()
bar()

在IDE中，代码输出

你好，我是foo，爸爸是 你好，我是bar，爸爸是foo 你好，我是bar，爸爸是

@jeff-laughlin的回答很漂亮。我对它进行了轻微的修改，以达到我认为的目的:跟踪函数的执行，并捕获参数列表以及关键字参数。谢谢你@jeff-laughlin!

最让我惊讶的是，有一种方法可以在运行时拦截函数，检查它们，并基于此采取一些操作。另一件令人惊讶的事情是内部函数的内存地址两次都是相同的。有人知道这是为什么吗?在我能够理解这个装饰器/闭包魔法之前，我还有一段路要走。

你可以使用@Andreas Jung显示的方法获得它定义时的名称，但这可能不是调用函数时的名称:

import inspect

def Foo():
   print inspect.stack()[0][3]

Foo2 = Foo

>>> Foo()
Foo

>>> Foo2()
Foo

这种区别对你来说是否重要，我不能说。

我把这个实用工具放在附近:

import inspect
myself = lambda: inspect.stack()[1][3]

用法:

myself()
