Set literals are available on all supported Python versions. They are
idiomatic and always faster:
$ python3 -m timeit '{}'
10000000 loops, best of 3: 0.0357 usec per loop
$ python3 -m timeit 'dict()'
10000000 loops, best of 3: 0.104 usec per loop
$ python3 -m timeit '{1, 2, 3}'
10000000 loops, best of 3: 0.0754 usec per loop
$ python3 -m timeit 'set([1, 2, 3])'
1000000 loops, best of 3: 0.228 usec per loop
It is possible that a key in a MultiValueDict has multiple values, lists
are represented this way. When accessing a key in a MultiValueDict
it only returns the last element of that key. This becomes a problem
when parsing an html dict with a list inside of it.
To fix this problem we have to get and set the value using .getlist()
and .setlist().
* Get rid of runtests.py
* Moved test code from rest_framework/tests and rest_framework/runtests to tests
* Invoke py.test from setup.py
* Invoke py.test from Travis
* Invoke py.test from tox
* Changed setUpClass to be just plain setUp in test_permissions.py
* Updated contribution guideline to show how to invoke py.test
