Description

The method cmp( ) compares two dictionaries based on key and values.

Syntax

Following is the syntax for cmp( ) method :

cmp(dict1, dict2)

Parameters

dict1 – This is the first dictionary to be compared with dict2.

dict2 – This is the second dictionary to be compared with dict1.

Return value :

This method returns 10 if both dictionaries are equal, – 1 if dictl < dict2 and 1 if dictl > dict2.

Example :

The following example shows the usage of comp( ) method.

# !/user/bin/python

dict1 = {‘Name’ : ‘Zara’, ‘Age’ : 7};

dict2 = {‘Name1 : ‘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 (dictl, dict4)

Let us compile and run the above program, this will produce the following result :

Return Value : – 1 .

Return Value : 1

Return Value : 0
