As mentioned in the previous chapter, variables are widely used for storing values for future usage. There are some restrictions and specifications for variable names in Python:

• A variable name can contain letters, numbers, or underscores
• A variable name cannot start with a number
• Variables are case-sensitive, i.e., Var and var are two different variables
• No special characters other than underscore _ are allowed
• You can't use reserved keywords as variables' names (such as, if, while, for, try, ...)
