推荐答案

• 因为它在你的命名空间中放入了很多东西(可能会影响之前导入的一些其他对象，而你不会知道它).

  • Because it puts a lot of stuff into your namespace (might shadow some other object from previous import and you won't know about it).

    因为您不确切知道导入了什么，并且无法轻松找到某个内容是从哪个模块导入的(可读性).

    Because you don't know exactly what is imported and can't easily find from which module a certain thing was imported (readability).

    因为你不能使用像 pyflakes 这样很酷的工具来静态检测代码中的错误.

    Because you can't use cool tools like pyflakes to statically detect errors in your code.
