[FIXED] How to get the nth element of a python list or a default if not available

Issue

I'm looking for an equivalent in python of dictionary.get(key, default) for lists. Is there any one liner idiom to get the nth element of a list or a default value if not available?

For example, given a list myList I would like to get myList[0], or 5 ifmyList is an empty list.

Thanks.

Solution

l[index] if index < len(l) else default

To support negative indices we can use:

l[index] if -len(l) <= index < len(l) else default
