Can Python create object by name? Like
clsName = "ClassA"
aObj = createObjectByName(clsName)
> pass

>>> # The class is in the globals() dict.
>>> globals()["MyClass"]

>>> # And also the locals() dict.
>>> locals()["MyClass"]

>>> # Create an instance via the globals() dict.
>>> globals()["MyClass"]()

>>> # Or via the locals() dict.
>>> locals()["MyClass"]()

if you are talking about creating an objcet dynamically and naming the
CLASS name at runtime, use:
If you know the name of the class and you want to get an instance
(object) of it dynamically, there are two ways I have found.

1) use getattr(module, "Class A").

2) Use the globals() dict which is handy when you know the class is
always in the same module as the code that calls it (watch out for
inheritance across more than one module though. This can put the
globals() call in a different module.)
