# Python Comparison Operators Example

Advertisements

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 −

Operator | Description | Example |
---|---|---|

== | If the values of two operands are equal, then the condition becomes true. | (a == b) is not true. |

!= | If values of two operands are not equal, then condition becomes true. | (a != b) is true. |

<> | If values of two operands are not equal, then condition becomes true. | (a <> b) is true. This is similar to != operator. |

> | If the value of left operand is greater than the value of right operand, then condition becomes true. | (a > b) is not true. |

< | If the value of left operand is less than the value of right operand, then condition becomes true. | (a < b) is true. |

>= | 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. |

<= | 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 −

#!/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 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
