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.
This tutorial covers arithmetic, comparison, Boolean, identity, membership, bitwise, concatenation, and repetition operators, along with augmented assignment operators. You’ll also learn how to build expressions using these operators and explore operator precedence to understand the order of operations in...

Precedence and Associativity of operators in Python Python Operator OverloadingBefore we wrap up, let’s put your knowledge of Python operators to the test! Can you solve the following challenge? Challenge: Write a function to split the restaurant bill among friends. Take the subtotal of the...
Operator precedence: In the absence of parentheses (within which expressions are first reduced), operators are executed left to right, first using** then*and/, and then +and -. Comparison operators on ints and floats i>j-returns True if strictly greater than ...

Operator precedence affects how an expression is evaluated, and == operator has higher precedence than not operator in Python. So not x == y is equivalent to not (x == y) which is equivalent to not (True == False) finally evaluating to True. But x == not y raises a SyntaxError ...
