I'm a little surprise
If "there should be one-- and preferably only one --obvious way to do
it" then my_list.clear() is more obvious than del my_list[:].
Honestly I'm a little surprised that such a topic hasn't been raised
before.

Who ever suggested that?
Note that the “OOW” in OOWTDI does *not* mean “Only One Way”. It
means “One Obvious Way”. Having other Ways To Do It is only mildly
deprecated, not forbidden.

Please don't post things like list before you do any research.
You don't know what you are talking about.

The usual answer to that is that there's already two ways of clearing a
list:

I see no reason that a list shouldn't have a .clear method.
Does dict have a .clear method? Yes.
Does set have a .clear method? Yes.
Does list have a .clear method? No.
Of course

Not very intuitive, though, until you learn the syntax.

learns about python anyway, and once you learn it,

It has:

Now, that could be useful, a writeline method that knew the EOL convention for
the OS and were not as deceiving as the current .writeline
