Assignment: Tic Tac Toe (part 1)

Due 10/9 at 11:59

Previously your projects have been simple enough to complete in one week, but now it’s time to turn up the heat 🔥

During the next two weeks, you will program a game of Tic, Tac, Toe to test your knowledge of functions. This week, you must submit a program that matches the following specifications:

• Define a function called print_column
  • Must have one parameter, piece
  • piece will be one of the following values:
    • None if no player has played on this cell yet
    • 'X' if the X player has played on this cell
    • 'O' if the Y player has played on this cell
  • Must print piece without printing a newline character
• Define a function called print_row
  • Must have one parameter, columns, which will be a list of 3 values
  • Must call print_column() 3 times, once for each piece in columns
  • The printed pieces must be separated by the | character
• Define a function called print_board
  • Must have one parameter, rows, which will be a list of 3 values
  • Must call print_row() 3 times, once for each value in rows
  • The printed rows must be separated by a line of - characters
• Call print_board() to print a test board to the console, like so:

  print_board([
    ['X', None, None],
    [None, 'O', 'X'],
    ['O', None, None],
  ])

  Which will result in somthing like the following output:

  -------------
  | X |   |   |
  -------------
  |   | O | X |
  -------------
  | O |   |   |
  -------------

Printing Without a Newline

So far, each time we have called print() it has automatically added a newline character to the end of whatever string we pass as an argument. However, according to the Python 3 docs we can provide a named argument for the parameter end to change what gets printed at the end of our string. Here is an example:

print('Hello, ', end='')
print('World!')
print('This is a new line.')

Which prints the following output:

Hello, World!
This is a new line.

Named arguments are a more advanced feature in Python. If you are curious, this article dives into different types of arguments and parameters.
