def tree(): return defaultdict(tree)

That's it!

Python packages for Data Analysis

Python packages for Data Analysis, Natural Language Processing, Machine Learning and Statistics

Forever a work in progress.

I recommend you install these from the python package manager - pip.

Keep in mind that you have to resolve the dependencies yourself(unless those dependencies are python packages), if you feel that you cannot do this then please install them from your distro's package manager.
