[已解决]python 用while语句编写99乘法表为什么不能呈现阶梯状

小孔爱学习

i = int(1)
while i <= 9:
    j = 1
    while j <= i:
        print(i,'X',j,'=',i*j,' ')
        j = j+1
    i = i+1

每个内循环需要加上 print 的 end 参数为 ''
不然会默认换行

1. i = int(1)
   
2. while i <= 9:
   
3.     j = 1
   
4.     while j <= i:
   
5.         print(i,'X',j,'=',i*j, end=' ')
   
6.         j = j+1
   
7.     print()
   
8.     i = i+1

这样既可了，默认情况下，print结束后自动换行，如果你不需要换行，需要手工填写end对应的标志
然后需要换行的时候，直接print()既可

1. for i in range(1, 10):
   
2.     for j in range(1, i+1):
   
3.         print(f"{i} × {j} = {i*j}", end = ' ')
   
4.     print()
