Question

def createList():
user_input = input("Enter a numbers seperated by a comma:")
user_list = user_input.split(',')
return user_list
def remove_duplicates(user_list):
test = []
for i in user_list:
if i not in test:
test.append(i)
x= print("Original List :",user_list)
y= print("List after removing duplicates:", test)
return x,y
def main():
createList()
remove_duplicates(user_list)
main()

why isnt user_data being passed through to remove_duplicates(user_list)? Explanation too please

Answer 1

This is because you were not capturing the user_list returned by the method createList().

Modified Code

def createList():

user_input = input("Enter a numbers seperated by a comma:")

user_list = user_input.split(',')

return user_list

def remove_duplicates(user_list):

test = []

for i in user_list:

if i not in test:

test.append(i)

x= print("Original List : ",user_list)

y= print("List after removing duplicates:", test)

return x,y

def main():

user_list = createList() ## only change that I did

remove_duplicates(user_list)

main()
