Python: Create a dictionary of keys x, y, and z
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:
# Import the 'pprint' function from the 'pprint' module to pretty-print dictionaries.
from pprint import pprint
# Create a dictionary 'dict_nums' with keys 'x', 'y', and 'z', and lists of numbers as values.
dict_nums = dict(x=list(range(11, 20)), y=list(range(21, 30)), z=list(range(31, 40)))
# Pretty-print the 'dict_nums' dictionary to improve readability.
pprint(dict_nums)
# Print the value at the 4th index of the 'x', 'y', and 'z' lists in 'dict_nums'.
print(dict_nums["x"][4])
print(dict_nums["y"][4])
print(dict_nums["z"][4])
# Iterate through the key-value pairs in 'dict_nums' and print the key and its associated value.
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]
