python中用代码实现99乘法表

for x in range(1,10):
    for y in range(1,x+1):
        print("%s*%s=%s" % (y,x,x*y),end=" ")
    print("")#print默认参数"换行",没有此条语句输出打印时将不会换行

for x in range(1,9):
    y=1
    while y<=x:
        print("%s*%s=%s" % (y,x,x*y),end=" ")
        y+=1
    print("")

print(‘\n‘.join([‘\t‘.join(["%2s*%2s=%2s"%(j,i,i*j) for j in range(1,i+1)]) for i in range(1,10)]))
