In Python, operator precedence follows the PEMDAS rule, which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. This rule dictates the order in which operations are performed in an expression. Operations enclosed in parentheses are executed first, followed by ...
Python 2.4 Operator Precedence Operator Precedence#运算优先级 Operator precedence is a very important concept in programming. It is an extension of the mathematical idea of order of operations (multiplication being performed before addition, etc.) to include other operators, such as those in Boolean ...

Explore Python operator precedence to understand how operators are evaluated in expressions. Learn the order of operations and improve your coding skills.
Take a quick interactive quiz on the concepts in Python: Operator of Precedence or print the worksheet to practice offline. These practice questions will help you master the material and retain the information.
You can surround the expression not True with parentheses (()) to fix this problem. This quick update tells Python to evaluate the parenthesized expression first.Among logical operators, not has higher precedence than the and operator and the or operator, which have the same precedence....

"Operator" 在英语中通常有两个主要含义。 首先,它是一个数学术语,表示一个运算符,也就是一种数学操作,比如加法、减法、乘法等。在编程中,它通常指的是一个可以执行某种特定操作的函数或方法。 其次,"Operator" 在计算机科学和编程中,特别是在某些编程语言如 Python 中,它也可以指代一个特定的操作符,如赋值操作...
