Python: Create a dictionary of keys x, y, and z

Python dictionary: Exercise-40 with Solution

Write a Python program to create a dictionary of keys x, y, and z where each key has as value a list from 11-20, 21-30, and 31-40 respectively. Access the fifth value of each key from the dictionary.

Sample Solution:

Python Code:

from pprint import pprint
dict_nums = dict(x=list(range(11, 20)), y=list(range(21, 30)), z=list(range(31, 40)))
pprint(dict_nums)
print(dict_nums["x"][4])
print(dict_nums["y"][4])
print(dict_nums["z"][4])
for k,v in dict_nums.items():
   print(k, "has value", v)

Sample Output:

{'x': [11, 12, 13, 14, 15, 16, 17, 18, 19],
 'y': [21, 22, 23, 24, 25, 26, 27, 28, 29],
 'z': [31, 32, 33, 34, 35, 36, 37, 38, 39]}
15
25
35
x has value [11, 12, 13, 14, 15, 16, 17, 18, 19]
y has value [21, 22, 23, 24, 25, 26, 27, 28, 29]
z has value [31, 32, 33, 34, 35, 36, 37, 38, 39]
