#用for 循环
for i in range(1,10):
    #print(i)
    # print(i*‘*‘)
    for j in range(1,i+1):
        print(‘%d * %d = %d‘%(j,i,i*j),end=‘  ‘)
    print(‘\n‘)

#用while 循环

i = 1
while i <= 9:
    j = 1
    # print(i)
    while j <= i:
        # print(j)
        print(‘%d * %d = %d ‘ %(j,i ,i*j),end=‘  ‘)
        j = j + 1
    print(‘\n‘)
    i = i +1
