How do you add input from user into list in Python
提问by pythonswag
print ('This is your Shopping List')
firstItem = input('Enter 1st item: ')
print (firstItem)
secondItem = input('Enter 2nd item: ')
print (secondItem)
How do I make a list of what the user has said then print it out at the end when they have finished?
如何列出用户所说的内容，然后在他们完成后将其打印出来？
Also how do I ask if they have added enough items to the list? And if they say no then it will print out the list of items already stored.
另外我如何询问他们是否在列表中添加了足够的项目？如果他们说不，那么它会打印出已经存储的项目列表。
Thanks, I'm new to this so I don't really know.
谢谢，我是新手，所以我真的不知道。

shopList.append(item)
print shopList
print "That's your Shopping List"
print shopList
