 if el1[i:i+len(el)] == el:
  • those. write after del el break? - Max
  • @ Max, for starters, it’s worth explaining what you are trying to do in this block of code ...;) PS break will only throw you out of the current cycle, and you have them nested - MaxU
  • thanks, I understood the error and already understood how to fix it - Max
  • @ Max, in my opinion, you are trying to invent a bicycle - read about Combinatoric iterators functions from the itertools module - MaxU
