TypeError: 'int' object is not iterable

def remove_duplicates(xlist):
    new_list = []
    return [x*y for x,y in xlist if y not in new_list.iteritems()]
 
print remove_duplicates([4,5,5,6])

i am trying to remove repeating numbers from a list that can be any size. but when I test out this idea i hit a brick wall. I get TypeError: 'int' object is not iterable. I have tried several alternatives as a single liner but was unsuccessful. Please can somone help me.

What end result are you looking for? The code segment for x,y in [1,2,3,4] will always fail.

>>> for x,y in [1,2]:
...     print x,y
...     
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> 

If you want to remove duplicates from xlist and keep the order of the sequence:

>>> output = []
>>> xlist = [1,2,3,5,5,5,6,6,7,8,8]
>>> for item in xlist:
...     if item not in output:
...         output.append(item)
...         
>>> output
[1, 2, 3, 5, 6, 7, 8]
>>> 

Are you trying to do this?

>>> output
[1, 2, 3, 5, 6, 7, 8]
>>> reduce(lambda x,y: x*y, output)
10080
>>>
