我在pycharm 3.8中处理异常时遇到了困难。

当我按ctrl+c运行我的程序时，它不工作，所以有人告诉我用pycharm控制台来测试，它确实工作，中断了键盘输入。

def readFloat(msg):
    while True:
            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}')
但现在，当我尝试Control+C时，它没有捕捉到我的除外，也没有打印我的自定义错误报告，返回0。

console_thrift.KeyboardInterruptException: KeyboardInterruptException()
所以我试着添加一个通用的异常，只是为了打印错误类，结果是这样的。
Error found: <class 'console_thrift.KeyboardInterruptException'>
所以我不能设法检测到一个除键盘中断并与之合作，只是使用一个通用的异常，有什么想法？
我添加的唯一一个插件是一个主题用户界面，用于完全黑色地运行pycharm，其余的都是安装时附带的，我想。我用CMD运行了.py文件，它工作得很好，可以检测到键盘中断。

Try this:
    from console_thrift import KeyboardInterruptException as KeyboardInterrupt
except ImportError:
