InspectorTiger

IT，Inspector Tiger，是一个现代Python代码审查工具/框架。它包含一系列预定义的处理程序，可以提醒您注意改进和可能的错误。除了这些处理程序，您还可以编写自己的或使用社区的处理程序。

ALPHABET = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"


class Foo(SomeObjects):
    def bar(self, x=[], y: Union[int, None] = None):
        x.append(1)
        for _ in range(3):
            try:
                super(bla, bla).foo_baz()
            except Exception:
                print("An exception")
            except AttributeError:
                print("An attribute error")
            finally:
                continue

        my_iterable = list(token[0] for token in tokens)
        for a in my_iterable:
            yield a

        my_other_iterable = list(map(itemgetter(0), tokens))
        for a in range(len(my_other_iterable)):
            print(a, "=>", my_other_iterable[a])

考虑这段代码，您看到了一些错误或改进，对吧？但如果在您的大型代码库中有数百行这样的代码，您会如何找到这些模式呢？通过编写正则表达式查询？LOL，当然不是。
