python实现6种方法打印九九乘法表

# ⽅法1，使⽤while嵌套# j = 0

# while j < 9:# j += 1

# # 内循环控制⾏# i = 0

# while i < j:# i += 1

# print(i, '*', j, '=', (i * j), end=' ')# print()

# ⽅法2，使⽤for语句# for i in range(1, 10):

# for j in range(1, i + 1):

# print('{}x{}={}\'.format(j, i, i * j), end='')# print()

# ⽅法3，使⽤while...for语句# i = 1

# while(i <=9):

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

# ⽅法4，使⽤for...while语句# for i in range(1,10):# j = 0

# while j < i:# j += 1

# print(\"%d*%d=%-3d\"%(i,j,i*j),end='')# print( )

# ⽅法5，定义⼀个变量

# a = [1, 2, 3, 4, 5, 6, 7, 8, 9]# for i in a:# j = 1

# while j <= i:

# print('%d*%d=%-3d'%(i,j,i*j),end='\')

# # %-3d 是控制输出结果占据3位，且从左⾯开始对齐# j += 1# print( )

# ⽅法6，使⽤⼀⾏语句

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