I always confuse between print vs return how do I know when will be the right choice to use return and when will be the right choice to use print?

Some statements return a value:
new_list = list(word) # returns a list which is pointed to by new_list
other_list = new_list.sort() # sorting happens "in place" so nothing is returned and other_list is pointed to None
A print statement has a return value of None. So a statement like:
return print("Hello")
Would also return None
