Variables in Python Programming
In programming, a "variable" is a container in which a data value can be stored within the computer’s memory. The stored value can then be referenced using the variable’s name. Data to be stored in a variable is assigned in a Python program declaration statement with the = assignment operator. For example, to store the numeric value 25 in a variable named "a":
- Variables are containers for storing data values. Python has no command for declaring a variable.
- A variable name must start with a letter or the underscore (_) character
- A variable name cannot start with a number
- A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _)
- Variable names are case-sensitive (name, Name and NAME are three different variables)
