Question

我试图从for循环中的数组中跳过一个值（或一次2个）。请参考以下代码：

loop = True
product = ['p3','p5','p7','16GB','32GB','1TB','2TB','19in','23in','Mini Tower', 'Midi Tower', '2 ports','4 ports']
while loop:
  for i in product:
    print('Would you like the following component: ',i,)
    input()
    if input == 'y':

如果他们选择那部分，我想跳到下一个部分。我有什么方法可以在循环中做到这一点？谢谢你的帮助！

您可以通过设置跳过标志来执行此操作，如果它为True，则不执行下一次迭代：

product = ['p3','p5','p7','16GB','32GB','1TB','2TB','19in','23in','Mini Tower', 'Midi Tower', '2 ports','4 ports']

skip = False
for i in product:
  if skip:
    print("Skipping: " + i)
    skip = False
    continue
  if input('Would you like the following component: ' + i) == 'y':
    print("Selected: ", i)
    skip = True

但是我猜你是想让这个人选择处理器，内存，屏幕等 - 这实际上是多个问题，每个问题都有多个选项。在这种情况下，我建议将其拆分为嵌套列表，并在每个选择之后停止 - 例如：

product = [['p3','p5','p7'], ['16GB','32GB','1TB','2TB'], ['19in','23in'], ['Mini Tower', 'Midi Tower'], ['2 ports','4 ports']]

for part in product:
  for i in part:
    if input('Would you like the following component: '+i) == 'y':
      print("Selected: ", i)
      break
