Python library to break text into words
I bought some e-books in a Humble Bundle. The file names are shown below. I would like to hyphenate words within the file names, so that the first three titles are a_devils_chaplain.pdf atomic_accidents.pdf chaos_making_a_new_science.pdf Is there a Python library that uses intelligent guesses to break sequences of characters into words?

The way to think of him is like Linus Torvalds of Linux. Most of his keynote at that conference was answering questions from the people who had attended. And he actually said, "Let's alternate between men and women asking questions."On the second day of the conference, he was wearing a shirt from PyLadies, another nonprofit like Django Girls that helps women learn how to program on Python. * This not "equal opportunity". It is a quota system. It's my impression that in the U.S., Asians are over-represented among programmers relative to their share of the population and that whites and especially blacks are under-represented.

It's silly to say that just because a group is over-represented that it "dominates". If a conference has more Asians than whites does that necessarily make it Asian-dominated? > And it is far more equal opportunity than having 25 males ask questions > and only one or two females. Not if there are 25 males with questions and only one or two females with questions. Among the people who have questions, you could choose randomly.

The sex disparity in Python and in tech in general could be due in part to discrimination, but it could also be due to different male and female interests and (gasp) aptitudes on average. Are Asian-Americans over-represented in tech because whites have been suppressed? There are far more female than male teachers. I don't attribute it to anti-male suppression but to greater female interest in working with children. In our public middle school (grades 6-8, ages 11-13) there is a programming club that is open to girls. My son is shut out because of his sex. That is just as wrong as excluding him because of his skin color. I oppose such discrimination. -- https://mail.python.org/mailman/listinfo/python-list
Intel Distribution for Python
The Intel Distribution for Python 2017 Beta https://software.intel.com/en-us/python-distribution is available for Windows, Linux, and Mac OS for Python 2.7 and 3.5. "The Beta product adds new Python packages like scikit-learn, mpi4py, numba, conda, tbb (Python interfaces to Intel® Threading Building Blocks) and pyDAAL (Python interfaces to Intel® Data Analytics Acceleration Library). The Beta also delivers performance improvements for NumPy/SciPy through linking with performance libraries like Intel® MKL, Intel® Message Passing Interface (Intel® MPI), Intel® TBB and Intel® DAAL."

Quandl is a good packages for importing financial and economic data. Quantopian is a site that lets you backtest strategies coded in Python. IBpy is a package for trading at Interactive Brokers using Python. Quantstart has e-books and a blog about Python in finance.

If 80% of Python programmers and potential speakers at a Python conference are male, the chance of 4 out 6 speakers being female is fairly low if gender is ignored. Some people think gender diversity in tech is so important that there should be gender preferences -- see for example this post by a Python blogger http://ilovesymposia.com/2015/04/03/calling-out-scipy-on-diversity/ .
