Describes how yield from keyword works and behaves in Python3

yield_from.py

""" while reading about yield keyword, I got curious about the difference between a yield and a yield from keywords.
    Here is a brief differentiation that I have shown.
"""
#a normal yield inside a function that takes a list as an input
def a_func(my_list):
  yield my_list
  
#using yield from keyword on a similar function
def b_func(my_list):
  yield from my_list
  
#the difference is evident when we iterate over these functions, let's see.
for a in a_func(["rahul","lakhanpal']):
  print(a)
#gives output
["rahul","lakhanpal"]

for b in b_func(["rahul","lakhanpal"]):
  print(b)
#gives output
rahul
lakhanpal
