Built-in function to get value of object if callable?

Question

class Thing():
    xyz = "I'm a string"

class Truc():
    def xyz(self):
        return "I'm a function"

def valueOrCalledValue(input):
    if callable(input):
        return input()
    else:
        return input

thing = Thing()
print valueOrCalledValue(thing.xyx)

>>> "I'm a string"

truc = Truc()
print valueOrCalledValue(truc.xyz)

>>> "I'm a function"

Is there a built-in function that does what my valueOrCalledValue does?

Answer 1

Try properties using decorators to make it tidy.

Answer 2

I don't know any built-in function to do that. Alternatively, you could do this in one line using a "if else" expression:

print my_thing() if callable(my_thing) else my_thing

assigning it to a variable works the same way:

my_var = my_thing() if callable(my_thing) else my_thing

Answer 3

Use this. It's simpler and always works for all possible variants on "callable".

def valueOrCalledValue(input):
    try:
        return input()
    except TypeError:
        return input
