[Python-Dev] annoying dictionary problem, non-existing keys
i use dictionaries to hold some config data,
such as:
conf={'key1':'value1','key2':'value2'}
and so on...
when i try to process conf, i have to code every time like:
if conf.has_key('key1'):
if conf['key1']<>'':
other commands
this is very annoying.
in php, i was able to code only like:
if conf['key1']=='someth'
in python, this fails, because, if key1 does not exists, it raises an exception.
MY question:
is there a way to directly get value of an array/tuple/dict item by key,
as in php above, even if key may not exist, i should not check if key exist,
i should only use it, if it does not exist, it may return only empty,
just as in php
i hope you understand my question...

> this is very annoying. Posting to so many lists is even more annoying. You might not get a single helpful answer just because people are so frustrated by this behavior.

Please consult the documentation first: http://docs.python.org/lib/typesmapping.html . You're looking for the get() method. This attribute of PHP is hardly considered a feature, and is not something Python wishes to emulate.
