- Concatenating two lists - difference between += and extend()

- Python: understanding difference between append and extend
list extend uses an iterable and adds all of it's elements to the end of your list: Extend the list by appending all the items in the given list; equivalent to a[len(a):] = L You need to use: sum_vec extend([vec1[i] + vec2[i]]) # note that a list is created That way an iterable with a single item (vec1[i] + vec2[i]) is passed

- Use of add(), append(), update() and extend() in Python
Similar differences apply to extend vs update Using the same name for operations with such drastically different semantics would be very misleading indeed it seems pythonic to just use a list on the first pass and deal with the performance on a later iteration
