Another way to remove duplicate list

```auto
def remove_duplicate_list(duplicate_list = []):
    for i in range(len(duplicate_list) - 1, 0, -1):
        for j in range(0, i):
            if duplicate_list[j] == duplicate_list[i]:
                duplicate_list.pop(i)
                break
    return duplicate_list

```

Another way:

```auto
def remove_duplicates(l):
    uniques = []
    for item in l:
        if item not in uniques:
            uniques.append(item)
    return uniques

```
