List: Slicing and Indexing with Connect 4

In the program hangman.py we learned how to slice a string and indexing in the previous assignments, pig latin and swapping letters.

The Connect 4 program can be written using strings.
Here is a little help:

# Using strings:
connect_board = '''|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|'''

# what do the indices look like?

# |  1  |  3  |  5  |  7  |  9  | 11  | 
# | 15  | 17  | 19  | 21  | 23  | 25  | 
# | 29  | 31  | 33  | 35  | 37  | 39  | 
# | 43  | 45  | 47  | 49  | 51  | 53  | 
# | 57  | 59  | 61  | 63  | 65  | 67  | 
# |  1  |  2  |  3  |  4  |  5  |  6  | 
In the last row you have the column numbers.


print('Empty board: ')
print(connect_board)
print( ' 1 2 3 4 5 6 ')
print('\nThe length of the string is ',len(connect_board))


print('')
yesNo = 'y'
while yesNo == 'y':
    column = int(input("Enter the column number "))
    offset = 1
    if column == 2:
        offset = 3
    elif column == 3:
        offset = 5
    elif column == 4:
        offset = 7
    elif column == 5:
        offset = 9
    elif column == 6:
        offset = 11
    empty = True
    position = offset + (14 * 4)
    while empty:
        if connect_board[position] == '_':
            connect_board = connect_board[:position] + 'A' + connect_board[position + 1:]
            print(connect_board)
            print( ' 1 2 3 4 5 6 ')
            empty = False
        else:
            position -= 14

    yesNo = input('More? ')

A test run could look like this:

Empty board: 
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
 1 2 3 4 5 6 


Enter the column number 1
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|A|_|_|_|_|_|
 1 2 3 4 5 6 
More? y
Enter the column number 1
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|_|_|_|_|_|_|
|A|_|_|_|_|_|
|A|_|_|_|_|_|
 1 2 3 4 5 6
