[issue23061] Update pep8 to specify explicitly 'module level' imports at top of file

[Terry J. Reedy]

Terry J. Reedy added the comment:

I read Nick's post and I would like PEP8 to continue to discourage imports at class scope unless there is actually a use case.  I discovered yesterday that idlelib.ColorDelegator has several imports at the top of the module and more as the top of the class (of the same name).  I cannot think of any good reason for the split.
