Question

Your task in to design a game of Nim in Python. In this game “Two players take turns removing objects from distinct heaps or piles. On each turn, a player must remove at least one object, and may remove any number of objects provided they all come from the same heap/pile. The goal of the game is to avoid taking the last object.” (Wikipedia)

In your implementation of the game, there will be 3 piles of objects. At the start of the game, each of the three piles will be initialized by a random number of objects. Random number should be between 5 and 15. The players will take turn picking up objects from the piles. A player can even pick up all items from a single pile. The player that picks up last object (across all piles) loses.

You should use functions in the program. Functions must follow a good programming style, that is, any well-defined task which needs to be executed often, can be moved into its own function.

=====================PLEASE PROVIDE A CLEAR FLOWCHART FOR THE PROGRAM.=============================

SAMPLE OF THE PROGRAM ==================

===== Welcome to Nim Game =====

Here are the three piles
A: *******
B: *************
C: *********
(7, 13, 9)

Player 1, choose your pile (A, B, C): C
Choose how many objects to remove: 5
OK

A: *******
B: *************
C: ****
(7, 13, 4)

Player 2, choose your pile (A, B, C): krypton
ERR: Sorry, that is not a valid pile.
Player 2, choose your pile (A, B, C): A
Choose how many objects to remove: 7
OK
A:
B: *************
C: ****
(0, 13, 4)

Player 1, choose your pile (A, B, C): B
Choose how many objects to remove: alpha
ERR: Sorry, that is not a valid number.
Choose how many objects to remove: 10
OK

A:
B: ***
C: ****
(0, 3, 4)

Player 2, choose your pile (A, B, C): C
Choose how many objects to remove: 8
ERR: Sorry, there is not enough objects to remove in this pile.
Choose how many objects to remove: 4
OK

A:
B: ***
C:
(0, 3, 0)

Player 1, choose your pile (A, B, C): C
ERR: Sorry, this pile is already empty.
Player 1, choose your pile (A, B, C): B
Choose how many objects to remove: 1
OK

A:
B: **
C:
(0, 2, 0)

Player 2, choose your pile (A, B, C): B
Choose how many objects to remove: 2
OK

A:
B:
C:
(0, 0, 0)

Player 2 picked up the last object. <<< Player 1 >>> is the WINNER.

Thanks for playing. Goodbye.
