Comparison Operator

Comparison operators are used to compare two values. Tests numerical equalities and inequalities between two operands and returns a Boolean value. It returns either True or False according to the condition.

operator	Description	Example
==	If the values of two operands are equal, then the condition becomes true.	a == b
!=	If values of two operands are not equal, then condition becomes true.	a != b
>	If the value of left operand is greater than the value of right operand, then condition becomes true	a > b
<	If the value of left operand is less than the value of right operand, then condition becomes true	a < b
>=	If the value of left operand is greater than or equal to the value of right operand, then condition becomes true	a >= b
<=	If the value of left operand is less than or equal to the value of right operand, then condition becomes true	a <= b

Comparison Operator - Program Link

a=int(input())
b=int(input())
print("a==b?",a==b)
print("a!=b?",a!=b)
print("a<b?",a<b)
print("a>b?",a>b)
print("a<=b?",a<=b)
print("a>=b?",a>=b)

Output

# a=2 b=3
a==b? False
a!=b? True
a<b? True
a>b? False
a<=b? True
a>=b? False
