Variable name – Identifiers

Variable name is known as identifier. There are few rules that you have to follow while naming the variables in Python.

1. The name of the variable must always start with either a letter or an underscore (_). For example: _str, str, num, _num are all valid name for the variables.

2. The name of the variable cannot start with a number. For example: 9num is not a valid variable name.

3. The name of the variable cannot have special characters such as %, $, # etc, they can only have alphanumeric characters and underscore (A to Z, a to z, 0-9 or _ ).

4. Variable name is case sensitive in Python which means num and NUM are two different variables in python.

Python Variable Example

num = 100

str = "BeginnersBook"

print(num)

print(str)

Output:

Python variables
