Variables in Python refers to an object — an item or element that is stored in the memory.
They are containers used for storing data values . The values can be string, numeric or any combination of alphanumeric characters.
In Python we can use an assignment statement to create new variables and assign specific values to them.
- Variable declaration is implicit in Python, which means variables are automatically declared and defined when they are assigned a value the first time.
- Variables must always be assigned values before they are used in expressions as otherwise it will lead to an error in the program.
- Wherever a variable name occurs in an expression, the interpreter replaces it with the value of that particular variable.
Examples:
- gender = 'M'
- message = "Keep Smiling"
- price = 987.9
