例如：

试试下面的例子就明白了所有的Python编程语言提供的比较操作符：

#!/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"

当执行上面的程序它会产生以下结果：

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
