cmpspecifies a custom comparison function of two arguments (iterable elements) which should return a negative, zero or positive number depending on whether the first argument is considered smaller than, equal to, or larger than the second argument:cmp=lambda x,y: cmp(x.lower(), y.lower())....
To sort the dictionary by the value, we use value() function with sorted() function and to print the value we use ‘for loop’. Example # Python3# Sort or Order dictionary by values.# Initialized a dictionaryfruitscolor = {"Banana":"Yellow","Mango":"Green","Apple":"Red","Grapefruit...
