Question

How to call a function inside a (code of a) module dynamically?

For example:

class Class1(object):
    pass

class Class2(object):
    pass

# here I want to either instantiate object dynamically or dynamically pass 
# a Class1 or Class2 object to some other method/class inside this module code

Answer 1

You mean something like this?

>>> class Class1(object):
...     pass
... 
>>> class Class2(object):
...     pass
... 
>>> def foo(cls):
...     print cls
... 
>>> import random
>>> classes = {'Class1': Class1, 'Class2': Class2}
>>> dynamic_class = classes['Class%d' % random.randint(1, 2)]
>>> foo(dynamic_class())
<__main__.Class1 object at 0x10b44ab50>
