Converting a 1D Array of Strings to a 2D Array in Python
A few issues:


Probably better to follow pep8
This isn't a method, it is a function
When doing 2D numpy indexes, you can do twoDArray[x, y]
You don't really need a numpy array, a list of lists works just as well.  Or better yet just just translate the 2D index into a linear index mathematically.  This also avoids the substantial overhead of converting the list to a numpy array.  You could even use np.ravel_multi_index to do the 2D to 1D conversion for you.
