KeyboardInterrupt异常

Question

我很难处理pycharm 3.8中的异常：

当我按下运行我的程序的ctrl+c时，它不起作用了，所以我被告知要使用pycharm控制台来测试它，它确实工作，中断了键盘的输入。

def readFloat(msg):
    while True:
        try:
            return float(input(f'{msg}'))
        except (ValueError, TypeError):
            print(f'\033[31mError. Not valid.\033[m')
            continue
        except KeyboardInterrupt:
            print('\033[31mYou didn\'t type a number.\033[m')
            return 0


b = readFloat('Your Number: ')
print(f'\nThat\'s your number: {b}')

但是现在，当我尝试Control+C时，它不会捕获我的But并打印我的自定义错误报告，返回0。它给了我一些巨大的红色错误线：

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_bundle\pydev_umd.py", line 197, in runfile
    pydev_imports.execfile(filename, global_vars, local_vars)  # execute the script
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile
    exec(compile(contents+"\n", file, 'exec'), glob, loc)
  File "C:/Users/User/PycharmProjects/Curso/Aula 23/ex113.py", line 35, in <module>
    b = readFloat('Your Number: ')
  File "C:/Users/User/PycharmProjects/Curso/Aula 23/ex113.py", line 26, in readFloat
    return float(input(f'{msg}'))
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_bundle\pydev_stdin.py", line 64, in readline
    requested_input = self.rpc_client.requestInput()
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\pydev\_pydev_comm\pydev_transport.py", line 226, in _req
    return super(TSyncClient, self)._req(_api, *args, **kwargs)
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\third_party\thriftpy\_shaded_thriftpy\thrift.py", line 160, in _req
    return self._recv(_api)
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2020.1.1\plugins\python-ce\helpers\third_party\thriftpy\_shaded_thriftpy\thrift.py", line 192, in _recv
    raise v
console_thrift.KeyboardInterruptException: KeyboardInterruptException()

因此，我尝试添加一个泛型异常，只为了打印错误类，我得到了以下结果：

Error found: <class 'console_thrift.KeyboardInterruptException'>

因此，我无法检测到一个除keyboardInterrupt，并使用它，只是使用一个通用的异常，有什么想法吗？

编辑

我添加的唯一插件是一个主题用户界面，它可以运行完全黑色的吡喃，我认为其余的插件都是分期付款的。我使用CMD运行.py文件，它工作得很好，检测到键盘中断。

Answer 1

试试这个：

try:
    from console_thrift import KeyboardInterruptException as KeyboardInterrupt
except ImportError:
    pass

Answer 2

IDE的特点是，它们与正常运行不太一样，特别是在处理键盘字符时。按照按ctrl的方式，IDE认为您想要复制文本。python程序从未看到该字符。也许它在运行时会打开一个单独的窗口？然后在ctrl之前选择那个窗口。
