关于九九乘法表while和for

九九乘法表

普通那种我就不放上来了

记录一下

def _while():
    print("--------------------------------开始了---------------------------------")
    print("=================================one==================================")
    i = 1
    while i <= 9:
        j = i
        while j <= 9:
            print("{:2}x{}={:<3}".format(i, j, i * j), end='')
            j += 1
        i += 1
        print()
    print("=================================two==================================")
    i = 1
    while i <= 9:
        j = i
        k = 1
        while i > k:
            print("        ", end="")
            k += 1
        while j <= 9:
            print("{:2}x{}={:<3}".format(i, j, i * j), end='')
            j += 1
        i += 1
        print()
    print("--------------------------------结束了---------------------------------")

def _for():
    print("--------------------------------开始了---------------------------------")
    print("=================================one==================================")
    for i in range(1, 10):
        for j in range(i, 10):
            print("{:2}x{}={:<3}".format(i, j, i * j), end="")
        print()

    print("=================================two==================================")

    for i in range(1, 10):
        for k in range(1, i):
            print("        ", end="")
        for j in range(i, 10):
            print("{:2}x{}={:<3}".format(i, j, i * j), end="")
        print()
    print("--------------------------------结束了---------------------------------")


print("1代表while循环\n2代表for循环")
print("请输入你想的循环方式:", end="")
m=input()
if m=='1':
    _while()
elif m=='2':
    _for()
else:
    print("操作错误")
