Solution Exercise 112: code python to sort list values of given dictionary

Exercise 112

Given a dictionary d whose key values are lists. Write a Python program that transforms the dictionary d by sorting the lists. Example for the dictionary:

d = {'a1': [21, 17, 22, 3], 'a2': [11, 15, 8, 13], 'a3': [7, 13, 2, 11], 'a4': [22,14,7,9]}

The program should return the dictionary:

d = {'a1': [3, 17, 21, 22], 'a2': [8, 11, 13, 15], 'a3': [2, 7, 11, 13], 'a4': [7, 9, 14, 22]}

Solution

d = {'a1': [21, 17, 22, 3], 'a2': [11, 15, 8, 13], 'a3': [7, 13, 2, 11], 'a4': [22,14,7,9]}

# getting the dictionary values and keys by using the items() methode
for key , value in d.items():
    # sorting the list value
    value.sort()
    # updating the dictionary d
    d[key] = value
# display result
print("The new dictionary is d = " , d)
# The output is : The new dictionary is d =  {'a1': [3, 17, 21, 22], 'a2': [8, 11, 13, 15], 'a3': [2, 7, 11, 13], 'a4': [7, 9, 14, 22]}
