Python Logical Operators — Python interactive lesson

Logical operators are used to combine conditional statements. Python has three logical operators:

and - Returns True if both statements are true
or - Returns True if one of the statements is true
not - Reverses the result, returns False if the result is true

The and Operator

The and keyword is a logical operator, and is used to combine conditional statements. Both conditions must be true for the entire expression to be true.

The or Operator

The or keyword is a logical operator, and is used to combine conditional statements. At least one condition must be true for the entire expression to be true.

The not Operator

The not keyword is a logical operator, and is used to reverse the result of the conditional statement.

Combining Multiple Operators

You can combine multiple logical operators in a single expression. Python evaluates not first, then and , then or .

Truth Tables

Understanding how logical operators work with different values:

and Operator Truth Table

Condition 1	Condition 2	Result
True	True	True
True	False	False
False	True	False
False	False	False

or Operator Truth Table

Condition 1	Condition 2	Result
True	True	True
True	False	True
False	True	True
False	False	False

Using Parentheses for Clarity

When combining multiple logical operators, use parentheses to make your intentions clear and control the order of evaluation.

Example

temperature = 25

is_raining = False

is_weekend = True

if (temperature > 20 and not is_raining) or is_weekend:

  print("Great day for outdoor activities!")
