[issue6751] Default return value in ConfigParser

2010-08-07 Thread Juan Javier 

Juan Javier jjdomingu...@gmail.com added the comment:

I would like the method to have the exact same behavior as before if the 
default argument is not present, and return the given default value when 
deafult argument is present.

If you simply add a default keyword, it will always be present and you 
wouldn't know if the user wants the exception thrown or the default value 
returned.

Do you know how to program this using a default keyword argument?

Éric Araujo mer...@netwok.org added the comment:

Why is it needed to add varargs and kwargs instead of only a new “default” 
argument?

Juan Javier jjdomingu...@gmail.com added the comment:

I've applied the enhancement to the three parsers, actually I've made the 
change to RawconfigParser with a small change to ConfigParser.

I've also created some unit tests.

Amaury Forgeot d'Arc amaur...@gmail.com added the comment:

The idea is fine (dict.get also has a 'default' parameter) but this patch is 
very incomplete:
- the enhancement should be applied to the three Parsers
- it needs unit tests.

A short inline patch is proposed, would something like this be acceptable?

[issue6751] Default return value in ConfigParser

2009-08-21 Thread Juan Javier 

New submission from Juan Javier jjdomingu...@yahoo.com:

I think it is useful, at least for me, to add an argument, default, to
[Safe,Raw]ConfigParser.get that, if present, will be returned if the
methid fails to return the value.

That is, instead of rasing an exception, return default, if present.

It could be done overriding the get method in SafeConfigParser,
something like this:

class SafeConfigParser(ConfigParser):
def get(self, section, option, raw=False, vars=None, **kwds):
try:
return super().get(section, option, raw, vars)
except Exception as exc:
if default in kwds:
return kwds[default]
raise exc
