Following example to understand all the comparison operators available in Python programming language:

# !/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” 

When you execute the above program it produces 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
