What is the cmp function of Python dictionary? What does the cmp function do?

In today's article, we will learn about the built-in functions in the python dictionary. In this article, I will explain What is cmp in python, and pythoncmp()Method for parsing. Okay, without further ado, let’s get started with the article.

Description

The cmp() function of Python dictionary is used to compare two dictionary elements.

Syntax

cmp() method syntax:

cmp(dict1, dict2)

Parameters

dict1 - - Dictionary for comparison.

dict2 -- Dictionary to compare.

Return value

If the elements of the two dictionaries are the same, return 0, if dictionary dict1 is greater than dictionary dict2, return 1, if dictionary dict1 is less than dictionary dict2, return -1.

Example

The following example shows how to use the cmp() function:

# !/usr/bin/python
# -*- coding: UTF-8 -*-

dict1 = {'Name': 'Zara', 'Age': 7};
dict2 = {'Name': 'Mahnaz', 'Age': 27};
dict3 = {'Name': 'Abid', 'Age': 27};
dict4 = {'Name': 'Zara', 'Age': 7};
print "Return Value : %d" % cmp(dict1, dict2)
print "Return Value : %d" % cmp(dict2, dict3)
print "Return Value : %d" % cmp(dict1, dict4)

The output result of the above example is:

Return Value : -1
Return Value : 1
Return Value : 0
