I have a list that starts with zeros, has sporadic data, and then has
good data. I define the point at which the data turns good to be the
first index with a non-zero entry that is followed by at least 4
consecutive non-zero data items (i.e. a week's worth of non-zero
data). For example, if my list is [0, 0, 1, 0, 1, 2, 3, 4, 5, 6, 7, 8,
9], I would define the point at which data turns good to be 4 (1
followed by 2, 3, 4, 5).
I have a simple algorithm to identify this changepoint, but it looks
crude: is there a cleaner, more elegant way to do this?
>>> for ii,dummy in enumerate(retHist):
... if 0 not in retHist[ii:ii+5]:
... break
>>> del retHist[:ii]
Well, to the extent short and sweet is elegant...
