...benchmark points out:
I have run the benchmark on my machine with python 2.7 for the two solutions above (blue: pure python, first solution) (red, numpy solution) and for the standard solution based on itemgetter() (black, reference solution).
The same benchmark with python 3.5 showed that the met...

How can I retrieve the remote git address of a repo?
...
If you have the name of the remote, you will be able with git 2.7 (Q4 2015), to use the new git remote get-url command:
git remote get-url origin

Extract subset of key-value pairs from Python dictionary object?

How to index into a dictionary?

If you do care about the order of the entries, starting with Python 2.7 you can use collections.OrderedDict. Or use a list of pairs
l = [("blue", "5"), ("red", "6"), ("yellow", "8")]
if you don't need access by key. (Why are your numbers strings by the way?)

Serializing class instance to JSON
...on.dumps(obj, default=lambda x: x.__dict__)
Explanation:
Form the docs (2.7, 3.6):
``default(obj)`` is a function that should return a serializable version
of obj or raise TypeError. The default simply raises TypeError.
(Works on Python 2.7 and Python 3.x)
Note: In this case you need instance...
How do I detect the Python version at runtime? [duplicate]
...r. sys.version_info[1] would give you the minor version number.
In Python 2.7 and later, the components of sys.version_info can also be accessed by name, so the major version number is sys.version_info.major.

Mapping over values in a python dictionary
...:
my_dictionary = {k: f(v) for k, v in my_dictionary.items()}
In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn't introduced until python 2.7.
Note that there is no such method on lists either; you'd have to use a list comprehension...
