L = somelist
idx = 0
while True:
item = L[idx]
# Do something with item
idx = (idx + 1) % len(L)
wouldn't it be cool if there was an itertool like this:
def circulate(L, begin = 0, step = 1):
idx = begin
while True:
yield L[idx]
idx = (idx + step) % len(L)
for x in circulate(range(10)):
print 'at', x,'!'
Or maybe someone knows an even better way of expressing the above code?
