What does newArray = myNumpyArray[:,0] mean?
Question: Not too familiar with Python and need to translate some code. Here is the gist
of what I am having a problem with:

    
    
    import numpy
    myNumpyArray = numpy.array([1,2,3,4])
    newArray = myNumpyArray[:,0]
    

I don't know what `myNumpyArray[:,0]` means and get compile error `IndexError:
too many indices`.


Answer: 
    myNumpyArray[:,0] 
    

means the first column of myNumpyArray, since your array is 1-Dimensional,
this doesn't work.
