[issue32300] print(os.environ.keys()) should only print the keys

[Serhiy Storchaka]

Serhiy Storchaka <storchaka+cpython at gmail.com> added the comment:

Don't make KeysView.__repr__ and ValuesView.__repr__ containing the lists of all keys and values. This will make the repr of the view of a mapping which is a proxy of an external DB containing the full content of that DB, which can be gigabytes. See for example rejected issue21670.
