Logical Operators
Logical operators are used to evaluate conditions and make decisions on the basis of results. They are
used on conditional statements and return either True or False. Python supports the following logical
operators:

Operator Name Description Example (x=2) Output

not NOT It reverses the result, returns false, if the not [(x < 5) and (x < 10)] False
result is true or vice versa.
and AND It returns true if both operands are true. (x < 5) and (x < 10) True
or OR It returns true if one of the operands is true. (x < 5) or (x < 2) True

PRECEDENCE OF OPERATORS

Precedence of operators determines the order in which the operators are executed. The operator
precedence in Python is listed in the given table. The highest precedence is at the top. The following
table shows the precedence of operators in Python:

Operator Name
() Parenthesis
** Exponent
*, /, %, // Multiplication, Division, Modulo, Floor Division

+, – Addition, Subtraction
==, !=, >, <, >=, <= Comparison
=, +=, -=, *=, /=, %=, **=, //= Assignment
