Generate Bingo cards using numpy arrays.
import numpy as np
import random
CARD_SIZE = 5
# Chooses from twice as many numbers as a card can have.
# For example, a card with size 5 can have numbers between 1 and 25*2 -> 50, inclusive (hence the '+ 1')
MIN = 1
MAX = CARD_SIZE**2 * 2 + 1
card = np.array( random.sample(range(MIN, MAX + 1), CARD_SIZE**2) ).reshape(CARD_SIZE, CARD_SIZE)
# Pretty print the card, using either (1) or (2)
# Choose one!
# (1) Print numpy's default string representation, with '[' and ']' removed
print np.array_str(card).replace('[', ' ').replace(']', '')
# (2) Iterate over each element in array
for row in card:
for element in row:
print element, '\t',
