How Does Operator Precedence Affect Expressions with \'in\' and Comparison Operators in Python?

Examining Operator Precedence: 'in' and Comparison Operators in Python

Python's operators follow a specific precedence order, which determines the order in which they are evaluated. This can be relevant when working with expressions involving multiple operators, such as 'in' and comparison operators.

In the example expression:

'1' in '11' == True

the 'in' and '==' operators have equal precedence and are evaluated from left to right. However, this is not the sole factor at play.

Chaining occurs when consecutive operators with the same precedence are encountered. In this case, the 'in' and '==' operators form a chain. Therefore, the expression is actually evaluated as:

('1' in '11') and ('11' == True)

Resulting in False, since '11' is not equal to True.

To avoid this, it is recommended to use parentheses to control the evaluation order. Alternatively, using the 'is' operator can ensure a direct comparison without chaining:

'1' in '11' is True
