exe_146_create_bingo_card.py

"""
A Bingo card consists of 5 columns of 5 numbers which are labelled with the letters B, I, N, G and O.

There are 15 numbers that can appear under each letter.

In particular, the numbers that can appear under the B range from 1 to 15,
the numbers that can appear under the I range from 16 to 30,
the numbers that can appear under the N range from 31 to 45, and so on.

Write a function that creates a random Bingo card and stores it in a dictionary.

The keys will be the letters B, I, N, G and O.
The values will be the lists of five numbers that appear under each letter.
Write a second function that displays the Bingo card with the columns labelled appropriately.

Use these functions to write a program that displays a random Bingo card.

Ensure that the main program only runs when the file containing your solution
has not been imported into another program.
