Comparison Operators in Python Class 11 Important Notes with Questions

Comparison Operators in Python

What are Operators ?

Operators are special symbols which perform a special task on values or variables. Same operator can behave differently on different data types.

What do you mean by Operand?

Operands are the values or variables on which the operator operate.

What do you mean by Expression in python?

Operators when applied on operands form an expression. for example

a = c – d

Identify the operator and operand in the following expression.

1) d = a * b

Here d, a, b are operands and = , * are operators

2) c = a + b

Here c, a, b are operands and =, + are operators

Operators are categorized as

1. Arithmetic

2. Relational

3. Logical

4. Assignment

Relational/Comparison Operators

Those operator which help to compare two or more values/variables are called Comparison Operators. The output of comparison operator is Boolean value(True or False).

Symbol	Name	Coding	Output
>	Greater than	>>> 6 > 9 >>> ‘CS’ > ‘cs’ >>> 2.4 > 5 >>>3.5 > (2.5 + 2) >>> 2.5 > ‘CS’	True False False False TypeError
<	Less than	>>> 9 < 2 >>> 7.5 < 12 >>> 10.6 < 5.6	False True False
>=	Greater than equal to	>>> 2 >= 6 >>> 5.2 >= 5.2 >>> “Hello” >= 2 >>> “Hello” >= “Hello”	False True TypeError True
<=	Less than equal	>>> 7 <= 2 >>> 7.0 <= 2 >>> ‘IP’ <= ‘ip’	False False True
!=	Not equals to	>>> 7 != 2 >>> ‘CS’ != ‘Cs’	True True
==	Equals to	>>> 2 == 3 >>> 2.0 == 3.0 >>> ‘CS’ == ‘Cs’	False False False

Q1. Evaluate the following

a) >>> 7 + 5 >= 10

Ans. True

b) >>> “Anil” > “anil”

Ans. False

c) >>> 25 % 3 == 2

Ans. False

d) >>> 23 // 7 >= 9

Ans. False

e) >>> 7 + 3 % 2 != True

Ans. True

f) >>> False == False

Ans. True

g) >>> True != False

Ans. True

h) >>> 78 % 9 % 2 == 0

Ans. True

i) >>> 29 == 89 % 30

Ans. True

j)>>> 45 // 68 % 2 == True

Ans. False
