...
1. Introduction
Here's a way to approach this problem systematically: if you have an algorithm that plays hangman well, then you can take the difficulty of each word to be the number of wrong guesses that your program would take if guessing that word.
2. Aside on hangman strategy

Difference between decimal, float and double in .NET?
...n a decimal form, and expect exact results in decimal representations; not all decimal numbers are exactly representable in binary floating point – 0.1, for example – so if you use a binary floating point value you'll actually get an approximation to 0.1.

With two arbitrary variables you could use ! to coerce them to boolean values and then u...
How to flatten only some dimensions of a numpy array
...an take -1 as an argument, meaning "total array size divided by product of all other listed dimensions":
e.g. to flatten all but the last dimension:

>>> new_arr.shape
# (5000, 25)
