Web16 hours ago · The simpler approach would be to use string slicing and a single loop. For this, you need to accumulate the respective start indices: def chunks (s, mylist): start = 0 for n in mylist: end = start + n yield s [start:end] start = end. The other approach would be to use an inner iterator to yield individual characters, instead of slicing.
