What Is Parentheses in Python?

() parentheses are used for order of operations, or order of evaluation, and are referred to as tuples. [] brackets are used for lists. List contents can be changed, unlike tuple content.

How do parentheses work in Python?

Python follows the same precedence rules for its mathematical operators that mathematics does. Parentheses have the highest precedence and can be used to force an expression to evaluate in the order you want. Since expressions in parentheses are evaluated first, 2 * (3-1) is 4, and (1+1)**(5-2) is 8.

Do you need parentheses in Python?

Although you need a pair of parentheses to print in Python 3, you no longer need a space after print , because it's a function. So that's only a single extra character. If you still find typing a single pair of parentheses to be "unnecessarily time-consuming," you can do p = print and save a few characters that way.
