还没有人提到operator.attrgetter：

>>> from operator import attrgetter
>>> l = [1, 2, 3]
>>> attrgetter('reverse')(l)()
>>> l
[3, 2, 1]
>>> 

答案（我希望）从来没有人想要

Eval样行为

getattr(locals().get("foo") or globals().get("foo"), "bar")()

为什么不添加自动导入

getattr(
    locals().get("foo") or 
    globals().get("foo") or
    __import__("foo"), 
"bar")()

万一我们有多余的字典要查

getattr(next((x for x in (f("foo") for f in 
                          [locals().get, globals().get, 
                           self.__dict__.get, __import__]) 
              if x)),
"bar")()

我们需要更深入

getattr(next((x for x in (f("foo") for f in 
              ([locals().get, globals().get, self.__dict__.get] +
               [d.get for d in (list(dd.values()) for dd in 
                                [locals(),globals(),self.__dict__]
                                if isinstance(dd,dict))
                if isinstance(d,dict)] + 
               [__import__])) 
        if x)),
"bar")()

给定一个字符串和一个函数的完整python路径，这就是我如何获得所述函数的结果：

import importlib
function_string = 'mypackage.mymodule.myfunc'
mod_name, func_name = function_string.rsplit('.',1)
mod = importlib.import_module(mod_name)
func = getattr(mod, func_name)
result = func()

试试这个。虽然这仍然使用eval，但它只使用它从当前上下文调用函数。然后，您就可以随心所欲地使用真正的函数了。

这对我的主要好处是，在调用函数时，您将得到任何与eval相关的错误。然后，当您调用时，只会得到与函数相关的错误。

def say_hello(name):
    print 'Hello {}!'.format(name)

# get the function by name
method_name = 'say_hello'
method = eval(method_name)

# call it like a regular function later
args = ['friend']
kwargs = {}
method(*args, **kwargs)

基于Patrick的解决方案，要动态获取模块，请使用以下方法导入：

module = __import__('foo')
func = getattr(module, 'bar')
func()

getattr根据对象的名称调用方法。但此对象应该是调用类的父对象。父类可以由super（self.__class__，self）获取

class Base:
    def call_base(func):
        """This does not work"""
        def new_func(self, *args, **kwargs):
            name = func.__name__
            getattr(super(self.__class__, self), name)(*args, **kwargs)
        return new_func

    def f(self, *args):
        print(f"BASE method invoked.")

    def g(self, *args):
        print(f"BASE method invoked.")

class Inherit(Base):
    @Base.call_base
    def f(self, *args):
        """function body will be ignored by the decorator."""
        pass

    @Base.call_base
    def g(self, *args):
        """function body will be ignored by the decorator."""
        pass

Inherit().f() # The goal is to print "BASE method invoked."
