Question

How to remove paired items in a list?

Let's say I have a list
List = [1,3,1,3,2, 1]
You need to remove 2 paired elements from the list
That is, first remove 1, 1. Then 3, 3.

The output should be [1,2]
The number 1 remains because she does not have a pair

Answer 1

There is a contradiction in your statement according which elements should be in the output. Can you check this please?

Answer 2

Sorry. I changed my question

Answer 3

for i in list:
if list.count(i)%2==0:
for j in range(list.count(i)):
list.remove(i)
for i in list:
if list.count(i)%2>=1:
for j in range(list.count(i)-1):
list.remove(i)

you convert it to a function.
print('good luck')

Answer 4

If you just want to remove duplications:

print(sorted(list(set(List))))

If you want to remove them completely:

print([i for i in List if List.count(i) == 1])
