I can’t figure out where’s wrong. I didn’t know about the statement “if x not in list” until recently. The results always return [].

def remove_duplicates(numbers):
  new_list=[]
  for x in numbers:
    for i in new_list:
      if x!=i:
        new_list.append(x)
  return new_list
print  remove_duplicates([1,2,2,3])

i added a print statement to your code:

def remove_duplicates(numbers):
  new_list=[]
  for x in numbers:
    for i in new_list:
      print "i get here"
      if x!=i:
        new_list.append(x)
  return new_list
print  remove_duplicates([1,2,2,3])

but we never see it. new_list is empty, so for i in new_list has nothing to do, so it won’t run.
