I am new to python and I am currently evaluating options and functionalities of
numerical programming and related 2d and 3d graphic outputs with python.
Kindly share your experience in scientific programming with python like how do

I want a dict() variant that passes these test cases:
map = Map()
assert not(map.has_key('_default'))

Indeed.
Because you can
You may want to look at the collections.defaultdict class. It takes in a
factory function for default values.
You can also implement your class by overriding the __missing__ method of
the dict class, rather than overriding the __getitem__.
Both were added in Python 2.5 according to the

Not everything needs to be a one liner. If you need this, do it the
old- fashioned way:

I already explained how to write it as a one-liner:

No, there never was; only between interpreting and compiling

Looks like a reasonable proposal, but coding this in C is a chore.
It's not that bad. Most C code is a bit of a chore compared to Python but it
