I haven't heard of any plans to deprecate the dictionary has_key
method, as the "in" keyword makes it obsolete.

i.e.
if key in dict:

instead of
if dict.has_key():


Is there some reason to keep has_key?

Two words: backward compatibility. To lose that method now would break thousands of existing programs. The 2.4 library would probably experience breakage too ... let's see:

$ find /lib/python2.4/ -name "*.py" -exec grep has_key {} \; | wc -l
587

Oops!

The method might disappear in Python 3.0, when we will be allowed to break backward compatibility - you are correct in saying it's no longer necessary.
