To remove duplicates from a list in Python, there are several methods you can use.
set()function returns a collection of unique elements. You can convert the list to a set, and then convert the set back to a list to remove duplicates. For example:
my_list = [1, 2, 3, 3, 4, 4, 5] my_list = list(set(my_list)) print(my_list) # [1, 2, 3, 4, 5]
Using a loop: You can loop through the list and append all unique elements to a new list. For example:
my_list = [1, 2, 3, 3, 4, 4, 5] new_list =  for i in my_list: if i not in new_list: new_list.append(i) print(new_list) # [1, 2, 3, 4, 5]
Using a list comprehension: You can use a list comprehension to define a new list with unique elements. For example:
my_list = [1, 2, 3, 3, 4, 4, 5] new_list = [i for n, i in enumerate(my_list) if i not in my_list[:n]] print(new_list) # [1, 2, 3, 4, 5]
Note that these methods preserve the order of the original list. If you don’t need to preserve the order, you can use the
set() function directly to remove duplicates, as shown in the first example above.
I hope this helps you to remove duplicates from a list in Python.
