How to replace __str__ for a function

Question

I want to change the string representation of a python function to be just the function name.

Eg for some function

 ...

Answer 1

class FNMagic:
     def __init__(self,fn,fn_name):
         self.fn = fn 
         self.fn_name = fn_name
     def __call__(self,*args,**kwargs):
         return self.fn(*args,**kwargs)
     def __str__(self):
         return self.fn_name


def blah(x):
    return x

blah = FNMagic(blah,"blah!")
print blah

you could make a simple decorator

class NamedFn:
    def __init__(self,name):
       self.fn_name = name
    def __call__(self,fn):
        return FNMagic(fn,self.fn_name)

@NamedFn("some_name!!!")
def blah2(x,y):
     return x*y

print blah2
