remove duplicates from list python
Example 1
from collections import OrderedDict alpList = ["a", "a", "a", "b", "c"] alpList = list(OrderedDict.fromkeys(alpList)) print(alpList) # ['a', 'b', 'c']
Example 2 Using sets
-
A set data type cannot store duplicates. So you can also use this method to remove duplicates from a list.
-
Be careful; the set() will change the order of the elements in the list.
from typing import List numbers: List[int] = [1,1,2,2,3,4,4,4,5,5,6,6,7,8,8] numbers = list(set(numbers)) print(numbers) # [1, 2, 3, 4, 5, 6, 7, 8]
Example 3 – Using List Comprehension

original = [1, 2, 3, 4, 5, 6, 5, 6, 4, 7, 8, 9, "a", "c", "b", "d", "c", "d"] temp = [] [temp.append(i) for i in original if i not in temp] print(temp) # [1, 2, 3, 4, 5, 6, 7, 8, 9, 'a', 'c', 'b', 'd']
