Write a Python function that takes a list and returns a new list with unique elements of the first list

example 1:-

def unique_list(l):
  x = []
  for a in l:
    if a not in x:
      x.append(a)
  return x

print(unique_list([1,2,3,3,3,3,4,5])) 

output:-

[1, 2, 3, 4, 5] 

example 2:-

def unique_list(l):
  num = []
  for a in l:
    if a not in num:
      num.append(a)
  return num
print('unique elements are')
print(unique_list([1,2,4,5,4,5,6,9,10]))

output:-

unique elements are
[1, 2, 4, 5, 6, 9, 10]
