# Let's say we wanted to print an array of the strings "p" and "q" that is
# 10 wide by 10 tall that looks like this:
"""
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
p q q q q q q q q q
"""

# One way to do is by using the following strategy.

# First, set the max size of width and height.
max_size = 10

# Then, set the starting point, which is the top left-most corner of the array.
row = 1
col = 1

# Do "something" so long as the the number of rows (the height of the array)
# is less than or equal to the maximum height specified.
while row <= max_size:

    # That "something", in this case, is print the string "p" followed by a
    # space. Then...
    print('p', end=' ')

    # Start a another loop inside of the first loop (see line 27) that does
    # "another thing" so long as the number of columns is less than the maximum
    # width specified.

    # *Note* that we are using "less than" rather than less than or equal to.
    # This is because the first column of this particular row was already
    # printed by the first loop.
    while col < max_size:

        # That "another thing", in this case, is print the string "q" followed
        # by a space.
        print('q', end=' ')

        # Then we increment the column number which is fed back into the
        # second while loop on line 40. This will continue to increment
        # until the the maximum width of the array is reached.
        col = col + 1

    # Once the maximum width for the row is reached, print an empty string
    # which will create a new line.
    print('')

    # Reset the column number to 1 because we that is where we want to start
    # printing the "q"s in the next row.
    col = 1

    # Increment the row number which will be fed back into the first while
    # loop on line 27.
    row = row + 1
