I'm looking at a way of cycling around a sequence i.e. starting at some
given location in the middle of a sequence and running to the end before
coming back to the beginning and running to the start place. About the
best I could come up with is the following, any better ideas for some
definition of better?
# quick&dirty
seq=range(10)
for x in seq[4:]+seq[:4]:
print x
# or
def oneround(seq, start=0):
i=start
l=len(seq)
while True:
yield seq[i]
i = (i+1) % l
if i==start: break
for x in oneround(range(50), 4):
print x
