Variable Names

When naming variables in Python, there are a few rules and best practices you should follow:

Must start with a letter or an underscore: Variable names cannot begin with a number. For example, _var and var are valid, but 1var is not.
Can contain letters, numbers, and underscores: You can use alphanumeric characters and underscores, such as var_1.
Case-sensitive: Python variables are case-sensitive, so Var and var would be two different variables.
No spaces: Variable names cannot contain spaces. Instead, use underscores, like my_variable.

Example of valid variable names:

Python

my_variable = 10
_variable = "Python"
Var123 = [1, 2, 3]
