为什么运行不了啊，新手自己琢磨的乘法口诀表
我想打个这样式的格式，打不出来，好难啊{:5_100:}{:10_266:}"C:\Users\Redmi G\Desktop\IMG_20230211_221032.jpg" a=1b=1
while b<10:
print(a,'*',b,'=',a*b,end=' ')
b+=1
print()
else:
a+=1
b=a
continue
while a==10:
break 本帖最后由 jackz007 于 2023-2-12 00:42 编辑
核心要点是，必须使用双层嵌套循环
b = 1
while b < 10:
a = 1
while a < b + 1:
print('%dx%d=%2d' % (a , b , a * b) , end = '')
a +=1
print()
b += 1
如果改用 for 循环，代码会更加简洁
for b in range(1 , 10):
for a in range(1 , b + 1):
print('%dx%d=%2d' % (a , b , a * b) , end = '')
print()
