Python Comparison Operators

Python Server Side Programming Programming

These operators compare the values on either sides of them and decide the relation among them. They are also called Relational operators.

Assume variable a holds 10 and variable b holds 20, then −

Sr.No	Operator & Description	Example
1	== If the values of two operands are equal, then the condition becomes true.	(a == b) is not true.
2	!= If values of two operands are not equal, then condition becomes true.	(a != b) is true.
3	<> If values of two operands are not equal, then condition becomes true.	(a <> b) is true. This is similar to != operator.
4	> If the value of left operand is greater than the value of right operand, then condition becomes true.	(a > b) is not true.
5	< If the value of left operand is less than the value of right operand, then condition becomes true.	(a < b) is true.
6	>= If the value of left operand is greater than or equal to the value of right operand, then condition becomes true.	(a >= b) is not true.
7	<= If the value of left operand is less than or equal to the value of right operand, then condition becomes true.	(a <= b) is true.

Example

Assume variable a holds 10 and variable b holds 20, then −

Live Demo

#!/usr/bin/python
a = 21
b = 10
c = 0
if ( a == b ):
   print "Line 1 - a is equal to b"
else:
  print "Line 1 - a is not equal to b"
if ( a != b ):
print "Line 2 - a is not equal to b"
else:
print "Line 2 - a is equal to b"
if ( a <> b ):
print "Line 3 - a is not equal to b"
else:
print "Line 3 - a is equal to b"
if ( a < b ):
print "Line 4 - a is less than b"
else:
print "Line 4 - a is not less than b"
if ( a > b ):
print "Line 5 - a is greater than b"
else:
print "Line 5 - a is not greater than b"
a = 5;
b = 20;
if ( a <= b ):
print "Line 6 - a is either less than or equal to b"
else:
print "Line 6 - a is neither less than nor equal to b"
if ( b >= a ):
print "Line 7 - b is either greater than or equal to b"
else:
print "Line 7 - b is neither greater than nor equal to b"

Output

When you execute the above program it produces the following result −

Line 1 - a is not equal to b
Line 2 - a is not equal to b
Line 3 - a is not equal to b
Line 4 - a is not less than b
Line 5 - a is greater than b
Line 6 - a is either less than or equal to b
Line 7 - b is either greater than or equal to b
