Empy a dictionary and a list in Python

Question

I know that a list/dictionary can be emptied by re-initializing new objects, but I want to keep the initial objects.

Also in Python 3 a list can be empty(removed) all elements, by using clear(). But how can be done in Python 2.7 ?
Remove all keys from a dictionary ?

For lists, see https://stackoverflow.com/questions/850795/different-ways-of-clearing-lists — mkrieger1, Oct 23 '19 at 09:54
[`dict.clear`](https://docs.python.org/2.7/library/stdtypes.html#dict.clear) exists in [tag:python-2.7]… — deceze, Oct 23 '19 at 09:55
