1. 获得先前退还的数值——A/63/43.2
原标题:Access a previously returned value - Python3.2

我一直试图让我能够了解我最近回来的价值,并在发言中加以使用,而不必回顾价值。

基本上,我有一段路段,要求有一个功能,使用户能够提供投入,然后将投入回馈到 lo中。

while selection() != 0: ## Calls the "WHAT WOULD YOU LIKE TO DO" list and if it is 0 quits the script
    input() ## just so it doesn t go straight away
    if selection.return == 1: ## This is what I would like to happen but not sure how to do it... I ve googled around a bit and checked python docs

参看:

if selection() == 1:

它将工作,但再次展示“WHAT WOULD YOU LIKE to DO”案文。

如果这是一个明显的解决办法,我会感到担忧,但会非常感激:

最佳回答

因此,你会把结果储存在一个变数中,因此,你可以在今后提及。 类似:

sel = selection()
while sel != 0:
    input()
    if sel==1:
        ...
    sel = selection()
问题回答

这只是对所张贴的回答的一种替代方法(对发表评论来说太迟),但请不改变你的答复: 无论你们是否喜欢,都只是选择优惠,但我不想重复投入来源线,尽管它“放弃”循环条件:

while True:
    sel = selection()
    if sel == 0: # or perhaps "if not sel"
        break
    input()
    if sel == 1:
        ...

幸福 co。
