Nov 18, 2024 · Using For Loop. To remove duplicates while keeping the original order, we can use a loop (for loop) to add only unique items to a new list. Python

Sep 13, 2021 · to use for loop try the below code: # old list mylist = [1,1,3,4,5,5,5,6] # create new list newlist = [] # Loop for each item inside the old list for x in mylist: #check if this item is not duplicate if x not in newlist: # add not duplicate item to new list newlist.append(x) print (newlist) Output:-[1, 3, 4, 5, 6]

Apr 26, 2017 · Here's the proper solution: i = 0. while i < len(a): j = i + 1. while j < len(a): if a[i] == a[j]: del a[j] else: j += 1. i += 1. This solution is in-place, modifying the original array rather than creating a new one. It also doesn't use any extra data structures. Thanks mate!

Nov 1, 2011 · Best approach of removing duplicates from a list is using set() function, available in python, again converting that set into list. In [2]: some_list = ['a','a','v','v','v','c','c','d'] In [3]: list(set(some_list)) Out[3]: ['a', 'c', 'd', 'v']

Learn how to remove duplicates from a List in Python. Remove any duplicates from a List: First we have a List that contains duplicates: Create a dictionary, using the List items as keys. This will automatically remove any duplicates because dictionaries cannot have duplicate keys. Then, convert the dictionary back into a list:

Oct 17, 2021 · Similar to the method using for loops, you can also use Python list comprehensions to deduplicate a list. The process involved here is a little different than a normal list comprehension, as we’ll be using the comprehension more for looping over the list. Let’s see what this looks like: print (deduplicated_list)

Write a function to remove duplicate elements from a list. Return the list without any duplicate elements sorted in ascending order. For example, for input [1, 2, 2, 3, 4, 4], the output should be [1, 2, 3, 4]. Did you find this article helpful? In this example, you will learn to remove duplicate elements from a list.

Three ways to remove duplicates from the list and those are: Using list comprehension. Few programming concepts you have to know before writing this program such as. new_list.append (i) print(f'your list {my_list}') print(f'list after removing duplicates {new_list}')

To remove duplicates from a list in Python, you can use methods like set(), dict.fromkeys(), list comprehension, or a loop to filter out duplicate elements. These techniques ensure that only unique elements remain in the list while preserving or discarding order as required based on the technique you are choosing.

Mar 21, 2025 · We can also use a loop to iterate through the list and remove duplicates manually. if element not in result: result.append(element) In this code: 1. We create an empty list result to store the unique elements. 2. Then, we iterate through each element in my_list. If the element is not already in result, we add it to result.
