Cool :-)
Both this and Hoyt's example do exactly what I want.
I'm guessing diff is going to be more efficient though?

Hi All,
Say I have an array like:
measurements = array([100,109,115,117])
What do I do to it to get:
array([9, 6, 2])
Is the following really the best way?
result = []
for i in range(1,len(measurements)):
... result.append(measurements[i]-measurements[i-1])
...
array(result)
numpy.diff

for i
Try
result = A[1:] - A[:-1]
