A variable is a storage area in computer program which holds some values – numbers, text or records.

Python is a dynamically typed i.e., you do not need to specify variable type during declaring.

How to create a Variable

To create a variable just assign it to a value, with a single equal(=) sign.

Ex –

>>num = 100
  • Python variable should be a name so we can find it again. Variable name should not be of reserved name.
  • White spaces and signs with special symbols like (+, – etc) not allowed.
  • You can use uppercase or lowercase and underscore(_) to have readability of a variable.
  • Variable names are case-sensitive in python.
