Is there any need of declaring a variable in python??

Question

Python

Answer 1

You don't need to declare anything before you really use it.

x = None
# ...
x = 1

The first line in this example is not need if you don't do anything with x unless line 3.

Answer 2

No, there is not. Actually the advantage of Python is you can assign a value to a variable (i.e. a string) and later re-assign another value even of a different type (i.e. integer).
