This is an exercise in the Automate The Boring Stuff book. I am supposed to create a function that takes a list value as an argument and returns a string with all the items separated by a comma and a space, with 'and' inserted before the last item. My code also includes a loop for the user to create their list.
def add_and(alist): if ((alist != ) & (len(alist) > 2)): for item in alist[:-1]: print(item + ", ",end="") print("and", alist[-1]) elif ((alist != ) & (len(alist) == 2)): print(alist, "and", alist) elif ((alist != ) & (len(alist) == 1)): print(alist) else: print("") your_list =  while True: print("Enter An Item or nothing") item = input() if ((item) == ""): print("") break else: your_list.append(item) continue add_and(your_list)
I know that the code works, but I was wondering if there were any faux-pas that I am implementing, or if there is anything I could obviously do to make it cleaner. Thanks!
