How to change function name dynamically in python

Question

I want to change the function name according to result obtained from another function but the function definition remains same How can i do this i tried the following example but it didn't work

def f(text):
   def x(text):
     return text+"example"
   name=x(text)
   def name(y):
     return y
   return name
p=f("hi ")
print p("hello")
print p.__name__

OUTPUT

hello
name

But i want the function name p.__name__ as "hi example" not name

Answer 1

You can simply assign to __name__:

def f(text):
   def r(y):
     return y
   r.__name__ = text + "example"
   return r
p = f("hi ")
print (p("hello")) # Outputs "hello"
print (p.__name__) # Outputs "hi example"

Note that a function name does not have any influence on the function's behavior though, and does not have any meaning except as a part of the string representation or a debugging aid.
