Remove Duplicates from Array in Python




Asked on August 18, 2023
I'm making an attempt to utilise Python to fix the duplicates in an array issue. I've discovered a few recommendations online, but I'm not sure which is the most helpful. Python Tutorial: Remove Duplicates from the Array is the piece I quoted.
One possibility is to use a set. A set is one type of data structure that exclusively stores solitary components. We can first make a set of the components of the array in order to build an array without duplicate elements.

def remove_duplicates(array):

seen = set()
  new_array = []
  for element in array:
    if element not in seen:
      seen.add(element)
      new_array.append(element)
  return new_array

The use of a hash table is another option. The term "hash table" refers to a type of data structure that links keys and values. A hash table can be used to turn each member of the array into a distinctive integer. After that, by repeating the procedure, we can add hash table elements to the new array that are just unique numerically.

def remove_duplicates(array):
  seen = {}
  new_array = []
  for element in array:
    if element not in seen:
      seen[element] = 1
      new_array.append(element)
  return new_array


Which of these strategies yields the best outcomes? Is there a better way to get rid of duplicates from an array in Python?
