Question

Does python have a function like call_user_func() in PHP?

PHP Version:

call_user_func(array($object,$methodName),$parameters)    

How do I achieve the above in Python?

Answer 1

Picking which object to instantiate isn’t that hard. A class is a first-class object and can be assigned to a variable or passed as an argument to a function.

class A(object):
    def __init__( self, arg1, arg2 ):
         etc.

class B(object):
    def __init__( self, arg1, arg2 ):
         etc.

thing_to_make = A
argList= ( some, pair )
thing_to_make( *argList )

thing_to_make = B
argList- ( another, pair )
thing_to_make( *argList )

def doSomething( class_, arg1, arg2 ):
    thing= class_( arg1, arg2 )
    thing.method()
    print thing

All works nicely without much pain. You don’t need a “call_user_function” sort of thing in Python
