I made example python list.

```
list_1 = [1,3,2,2,3,4,5,1]
print(list_1)

```

> 
> [1, 3, 2, 2, 3, 4, 5, 1]
> 
> 
> 

To remove overlap, i tried to use set().

```
print(set(list_1))

```

> 
> {1, 2, 3, 4, 5}
> 
> 
> 

but i want make 

```
[1,3,2,4,5]

```

I want remove overlap in list, but i also want order not to be changed.

How can i do that?
