Python is not “statically typed”. We do not need to declare variables before using them, or declare their type. A variable is created the moment we first assign a value to it.

Rules for creating variables in Python are same as they are in other high-level languages. They are:
a) A variable name must start with a letter or the underscore character.
b) A variable name cannot start with a number.
c) A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ).
d) Variable names are case-sensitive (name, Name and NAME are three different variables).
e) The reserved words(keywords) cannot be used naming the variable.
Assigning a single value to multiple variables:
Also Python allows to assign a single value to several variables simultaneously.

Can we use same name for different types?
If we use same name, the variable starts referring to new value and type.
How does + operator work with variables?
Can we use + for different types also?
No using for different types would produce error.
TypeError: unsupported operand type(s) for +: 'int' and 'str'
Creating objects (or variables of a class type):
