Hello, I am working on a problem (Bioinformatics domain) where all possible combinations of input string needs to be printed as sublist
For example: Input string : "LEQN" Output= "[L","E","Q","N"]["LE","EQ","QN","NL"] ["LEQ","EQN","QNE","NLE"] ["LEQN"] The code i have written for this is as follows: from itertools import chain, repeat, islice from collections import deque def sliding_window(iterable, n, fill=False, fillvalue=None): it = iter(iterable) if fill: it = chain(it, repeat(fillvalue, n - 1)) w = deque(islice(it, n - 1)) for x in it: w.append(x) yield w w.popleft() input="LENQ" lstinput= list(input) lenlstinput=len(lstinput) list1=[''.join(x) for x in sliding_window(lstinput, 2)] list2= [''.join(x) for x in sliding_window(lstinput, 3)] list3= [''.join(x) for x in sliding_window(lstinput, 4)] The output i get as follows: List 1 is ['LE', 'EN', 'NQ'] Should be ['LE','EN','NQ','QL'] List 2 is ['LEN', 'ENQ'] Should be ['LEN','ENQ','NQL','QLE'] So the question i am asking , how can i add wrapping around sublist in my sliding window function.
