Elegant way to unpack limited dict values into local variables in Python
python
Solution
You can do something like
foo, bar = map(d.get, ('foo', 'bar'))
or
foo, bar = itemgetter('foo', 'bar')(d)
This may save some typing, but essentially is the same as what you are doing (which is a good thing).
Problem
I'm looking for an elegant way to extract some values from a Python dict into local values. Something equivalent to this, but cleaner for a longer list of values, and for longer key/variable names: ``` d = { 'foo': 1, 'bar': 2, 'extra': 3 } foo, bar = d['foo'], d['bar'] ``` I was originally hoping for something like the following: ``` foo, bar = d.get_tuple('foo', 'bar') ``` I can easily write a function which isn't bad: ``` def get_selected_values(d, *args): return [d[arg] for arg in args] foo, bar = get_selected_values(d, 'foo', 'bar') ``` But I keep having the sneaking suspicion that there is some other builtin way.
