Python不调用变量（pycharm）

Question

有人知道在代码开头调用输入有什么不对吗？我让某人输入他们希望继续进行的号码，因为某些原因它不想这样做

我也得到了一个关于 如果感觉积极： 因为某些原因，我不能让它发挥作用

Answer 1

您正在将input()返回值转换为float，行-

Command = float(input())

然后根据字符串检查这个Command，行如下-

^{pr2}$

它们将不匹配，因为字符串永远不会等于float。你不需要做浮动转换-

Command = input()

---

另外，你应该修正缩进，缩进在Python中非常重要，它是用来定义块的。在

每个单独的块都应该从上一个块的特定级别缩进，建议缩进4个空格。在

对于评论中提到的第二个问题-

line 29 elif feeling in positive: ^ SyntaxError: invalid syntax

问题是一致的-

if feeling in negative:
    print ("Why is that", name)
reason = input()
while reason is "":
    print ("Why is that?")
reason = input()
elif feeling in positive:

这是因为有一个elif部分没有if部分。最有可能的情况是，您想缩进if块中的while部分，如果是的话，就将其缩进。在
