I can use x[::n] to select every nth element of a list. Is there a one-liner to
get a list that excludes every nth element?
Something like that:
>>> l = list("lkodjuyhrtgfedcvfg")
>>> l
['l', 'k', 'o', 'd', 'j', 'u', 'y', 'h', 'r', 't', 'g', 'f', 'e', 'd',
'c', 'v', 'f', 'g']
>>> ll = [c for i, c in enumerate(l) if i % 3]
>>> ll.insert(0, l[0])
>>> ll
['l', 'k', 'o', 'j', 'u', 'h', 'r', 'g', 'f', 'd', 'c', 'f', 'g']
