To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
If you like to have a function where you can send your lists, and get them back without duplicates, you can create a function and insert the code from the example above. Example defmy_function(x): returnlist(dict.fromkeys(x)) mylist =my_function(["a","b","a","c","c"]) ...
return list(dict.fromkeys(DUPLICATES)) Here is what the above code does: It creates a dictionary using fromkeys() method. Each element from DUPLICATES is a key with a value of None. Dictionaries in Python 3.6 and above are ordered, so the keys are created in the same order as they appea...
