我写了一个大约 100 行的 Python 程序，它只是没有从某个点运行

Question

我用python编写了大约100行的程序，其中大部分都在一个大函数中。它有很多if-elif和else语句，当我运行它时，一开始它看起来很有希望，但它停止了，没有错误，只是没有继续。我在VSCode中写了它，并试图在终端中运行它，但它不起作用。我在谷歌上搜索了一下，什么都没找到？它在第二个if语句之前停止，请帮忙！(我知道这可能不是一个好问题，但我真的不明白如何创建一个，请不要刻薄(请忽略打印文本，它是我的语言

Answer 1

您的if不执行编辑：实际上它确实执行了，但比较了错误的var类型，如下所述：(

ach = input("pentru distanta 1, penrtru mijloc 2: ") # input is string
if ach == 1:                                         # Checks for integer

解决方案：强制转换输入：ach = int(input(..))将ach与字符串ach == "1"进行比较。

p.s.干得好："Doamne fereste"字符串。将其替换为"Multa bafta pe viitor"。

编辑：您还应该检查其他进行输入和比较的地方，比如：

ach = input("pentru distanta 1, penrtru mijloc 2: ")
print(type(ach))
