Python打印九九乘法表有几种方式？

for i in range(1, 10):
    for j in range(1, i+1):
        print('{}x{}={}\t'.format(i, j, i*j), end='')
    print()

i = 1
while i <= 9:
    j = 1
    while(j <= i):
        print('%d*%d=%-3d' % (j, i, i*j), end='\t')
        j += 1
    print('')
    i += 1

i = 1
while(i <=9):
    for j in range (1,i+1): #range()函数左闭右开
        print('%d*%d=%-3d'%(j,i,i*j),end='')
    i += 1
    print()

for i in range(1,10):
    j = 0
    while j < i:
        j += 1
        print("%d*%d=%-3d"%(j,i,i*j),end='')
    print( )
