What are the precedence rules in Python?
In Python, operator precedence determines the order in which operations are performed. For example, multiplication has higher precedence than addition.
Can you give me an example of how precedence affects calculations?
Sure! In the expression 3 + 4 * 2
, the multiplication is performed first, so the result is 3 + 8
, which equals 11
.
What about parentheses? Do they change the precedence?
Yes, parentheses can change the precedence. In the expression (3 + 4) * 2
, the addition is performed first due to the parentheses, resulting in 7 * 2
, which equals 14
.
Are there any operators that have the same precedence?
Yes, some operators have the same precedence, such as addition and subtraction. In such cases, they are evaluated from left to right.
