Hi to all,
I've got an 1-D array of bools and I'd like to find the length of the first
contiguous sequence of True values, starting from position [0] of the array.
(That's equivalent to find the position of the first occurrence of False in
the array).
The problem is trivial, but I was wondering: what's the best (fastest,
cleanest, most pythonesque) way to do it in numpy? And what if I want to get
a list of all the contiguous sequences of True values, above a given
threshold?
Thanks in advance for your advices,
Chris.
