使用Python3打印九九乘法表的几种方法

这几天学习,遇到一个打印九九乘法表的题目.自己研究了几种方法,在这里分享给大家!

代码如下:

#3.打印九九乘法表
#方法一
print("<<九九乘法表>>")
for i in range(1,10):
    for x in range(1,i+1):
        print( '%d X %d = %2d' % (i ,x ,i*x) ,end = '  ' )
    print('  ')
#
print('-----------------------------------------------')
#
#方法二:
print(' 打印九九乘法表')

i = 1
while i <10:
    j = 1
    while j <i+1:
        print('%d X %d = %2d' %(i ,j ,i*j) ,end = '  ')
        j += 1
    i += 1
    print(' ')


print("---"* 20)

#
print('乘法表')
i = 1
while i <10:
    #print('\t|||')
    for j in range(1,i+1):
        print(' %d * %d = %2d' %(i, j , j* i),end ='\t')
    print('  ')

    i += 1

#同理做了一个加法口诀表

#打印加法口诀表
print('加法口诀表')
for i  in range(1,10):
    for j in range(1,i+1):
        #print("%d + %d = %2d " %(i , j ,i + j) ,end = '  ')
        print('{} + {} = {:2d} '.format(i , j , i + j) ,end = '  ')
    print('  ')

print('---'* 30)
