Record#

1. Today I learned about two-dimensional arrays. The first dimension of a two-dimensional array is a list, and the second dimension contains the information within the list.
2. For example: my2dlist = [["张三", 20], ["李四", 28]]. Print: print (my2dlist [0]) = [["张三", 20]]. print (my2dlist [0][0]) = 张三
3. Edit array: my2dlist [0][0] = "王五", print (my2dlist [0][0]) = 王五
4. Today's exercise was to print a bingo card. I spent half an hour writing it and couldn't get it right. The final correct answer didn't match the question. Maybe I overcomplicated it.

CODE#

import random

bingo = []

def ran():
  number = random.randint(1, 90)
  return number

def prettyPrint():
  for row in bingo:
    print(row)

numbers = []
for i in range(8):
  numbers.append(ran())

numbers.sort()

bingo = [[numbers[0], numbers[1], numbers[2]],
         [numbers[3], "BINGO", numbers[4]],
         [numbers[5], numbers[6], numbers[7]]
        ]

prettyPrint()
