def _yield(): for x in range(10): yield x def _return(): l = [] for x in range(10): l.append(x) return l yield_ = _yield() print(yield_) print(next(yield_)) print(list(yield_)) return_ = _return() print(return_) # https://www.quora.com/What-is-the-difference-between-yield-and-return-in-JUMP_LINK__&&__python__&&__JUMP_LINK

Simply, the yield function will return a genarator item instead of returning the whole list (look up on generator where it can be used for other iteration method). This is mainly used for saving memory space especially for when a large amount of data is being handled. For instance, def create_list(x): list = [] for i in range(x): list.append(i) return list def create_gen(x): for i in range(x): yield i where both functions can both be used in for loops eg. for i in create_gen(4): print(i) or for i in create_list(4): print(i) which give the same result >>> 0 1 2 3 >>> the create_list(x) will take up the amount of space based on the length of the list returned, whereas the create_gen(x) will return a generator where it will only take up the space of each item generated. NB: I am not a professional myself. If there is anything wrong here, I am very sorryy~ T-T https://pythontips.com/2013/09/29/the-JUMP_LINK__&&__python__&&__JUMP_LINK-yield-keyword-explained/
