This means that Python will multiply 3 by 1, resulting in 3, and then add 5 to 3, resulting in 8. Next, the * operator (multiplication) will be evaluated, followed by the + operator (addition). The // operator will then divide 4 by 4, resulting in 1. This means that Python will first evaluate 2 2, which results in 4. The operator precedence rules in Python dictate that the operator (exponentiation) has the highest precedence, followed by the // operator (floor division). The expression evaluates to the value of x, which is assigned the result of the expression. In this example, we have a series of operators used in a single expression, with each operator having its own precedence. Let’s take a look at an example of Python operator precedence to illustrate how it works in practice.Ĭode Implementation x = 5 + 3 * 2 ** 2 // 4 By using parentheses to group expressions together and ensuring that operators are evaluated in the correct order, we can avoid errors and improve the readability of our code. Understanding operator precedence rules is important for writing correct and efficient code. If two operators have the same precedence, they are evaluated from left to right. When evaluating an expression, Python will first evaluate any operators with higher precedence before evaluating those with lower precedence. Finally, the logical NOT (!) operator has lower precedence than any other operator, followed by the logical AND (&) and logical OR (||) operators. The comparison operators (=, !=, and =) have even lower precedence, followed by the identity operators (is and is not) and membership operators (in and not in). The bitwise shift operators () have lower precedence, followed by the bitwise AND (&), bitwise XOR (^), and bitwise OR (|) operators. The multiplication (), division (/), floor division (//), and modulo (%) operators have the next highest precedence, followed by the addition (+) and subtraction (-) operators. The * operator has the highest precedence, followed by the positive (+x) and negative (-x) operators. Multiplication, division, floor division, modulo The following table lists Python’s operators in order of precedence, from highest to lowest: Operator Operators with higher precedence are evaluated first, and those with lower precedence are evaluated later. Python has a well-defined set of operator precedence rules that determine the order in which arithmetic and logical operators are evaluated. In Python, operator precedence rules specify the order in which operators are evaluated in an expression. For example, multiplication is evaluated before addition, so the expression 2 + 3 4 would be evaluated as 2 + (3 4), resulting in 14. This means that some operators are evaluated before others, based on their level of precedence. Python uses a set of rules called "operator precedence" to determine the order in which operators are evaluated in an expression. In this article, we will discuss python operator precedence, Example of python operator precedence, and Application of python operator precedence. Understanding how Python evaluates expressions and the order in which it applies operators is critical to writing correct and efficient code. One of the key features of Python is its ability to process complex expressions using a variety of operators.
