Definition
Variables are named storage locations that hold data values. They make it easy to reuse and manipulate values without recalculating them repeatedly.
To create a variable, choose a name and use the equals sign = to assign a value to it. Make sure the variable name is descriptive.
12# Variable called `expenses` with value `1200` expenses = 1200
Variables can also be used to calculate and store new values based on existing ones. This makes the code more flexible and reduces the need for repetitive calculations. Using variables is really convenient, and you can also display their values using the print() statement.
123456789# Monthly expenses amount in dollars monthly_expenses = 1200 # Discount rate as a decimal (20%) discount_rate = 0.2 # Calculated total expenses after applying the discount total_expenses = monthly_expenses * (1 - discount_rate) print(total_expenses)
