Can anyone help me to debug this program? and please tell me the logic behind this code.
shopping_list = {}
def show_help():
print("\nseprate each iteam with a comma")
print("Type SHOW to show your current list, type DONE when you are finished and HELP to show this \n massage")
def show_list():
for item in shopping_list:
count = 1
print("{}: {}".format(count, item))
count+=1
print("Give me a list of things you want to shop for")
show_help()
while True:
new_stuff = input("> ")
if new_stuff == "DONE":
print("\nheres your list")
show_list()
break
elif new_stuff == "HELP":
show_help()
continue
elif new_stuff == "SHOW":
show_list
continue
else:
new_list = new_stuff.split(",")
index = input("Add this at a certen spot: press enter for the end of the list"
"or give a number, currently {} items in the list".format(len(shopping_list)))
if index:
spot = int(index) - 1
for item in new_list:
shopping_list.insert(spot, new_list.strip())
spot += 1
else:
for item in new_list:
shopping_list.append(item.strip())

shopping_list = [] # <-- #1 changed to list instead of dictionary
def show_help():
print("\nseprate each iteam with a comma")
print("Type SHOW to show your current list, type DONE when you are finished and HELP to show this \n massage")
def show_list():
count = 1 # <-- #2 moved count init outside of loop
for item in shopping_list:
print("{}: {}".format(count, item))
count+=1
print("Give me a list of things you want to shop for")
show_help()
while True:
new_stuff = input("> ")
if new_stuff == "DONE":
print("\nheres your list")
show_list()
break
elif new_stuff == "HELP":
show_help()
continue
elif new_stuff == "SHOW":
show_list() # <-- #3 added missing parens
continue
else:
new_list = new_stuff.split(",")
index = input("Add this at a certen spot: press enter for the end of the list"
"or give a number, currently {} items in the list".format(len(shopping_list)))
if index:
spot = int(index) - 1
for item in new_list:
shopping_list.insert(spot, item.strip()) # <-- #4 strip item instead of new_list
spot += 1
else:
for item in new_list:
shopping_list.append(item.strip())
