简易练习-3 99乘法表

用for迴圈, range()

for i in range(1, 10):    for j in range(1, 10):        num = i * j        print('%d x %d = %d' %(i, j, num))    print('\n')

用for迴圈, 但自定义list, 不使用range()

list = [1,2,3,4,5,6,7,8,9]for i in list:    for j in list:        num = i * j        print('%d x %d = %d' %(i, j, num))    print('\n')

用while迴圈

i = 1while i < 10:    j = 1    while j < 10:        num = i*j        print('%d x %d = %d' %(i, j, num))        j += 1    i += 1    print('\n')
