Lecture 22:- Logical Operators in Python
In Python, logical operators are used to perform logical operations on Boolean values (
TrueandFalse). These operators allow you to combine multiple conditions and evaluate the truth value of the expressions. There are three common logical operators in Python:
- Logical AND:
andTheandoperator returnsTrueif both conditions on its left and right sides areTrue, otherwise, it returnsFalse.Example:
pythonCopy code
x = 5 y = 10 result = (x < 10) and (y > 5) print(result) # Output: True result2 = (x < 4) and (y > 15) print(result2) # Output: False
- Logical OR:
orTheoroperator returnsTrueif at least one of the conditions on its left and right sides isTrue. It returnsFalseonly if both conditions areFalse.Example:
pythonCopy code
x = 5 y = 10 result = (x < 10) or (y < 5) print(result) # Output: True result2 = (x > 7) or (y < 5) print(result2) # Output: False
- Logical NOT:
notThenotoperator returns the opposite of the Boolean value. If the expression isTrue,notreturnsFalse, and if the expression isFalse,notreturnsTrue.Example:
pythonCopy code
x = 5 y = 10 result = not (x < y) print(result) # Output: False result2 = not (x > y) print(result2) # Output: TrueLogical operators are commonly used to make decisions and control the flow of programs based on multiple conditions. They are often used in combination with conditional statements (such as
if,elif, andelse) and loops to control the execution of code based on the outcome of the logical expressions.
