While this method will work for versions earlier than Python 3.7, the resulting deduplicated list will not maintain the order of the original list. Since Python 3.7, Python dictionaries maintain the original order of items passed into them. Use Python Dictionaries to Remove Duplicates from a List More of a visual learner, check out my YouTube tutorial here. Want to learn more about Python list comprehensions? Check out this in-depth tutorial that covers off everything you need to know, with hands-on examples. PASTEBOT NO DUPLICATE HOW TOIn the next section, you’ll learn how to use Python dictionaries to deduplicate a Python list. However, since we’re only looping over the list and appending to another list, no new list is instantiated using the comprehension. PASTEBOT NO DUPLICATE CODEThis can make the code less intuitive to follow, as list comprehensions are often used to create new lists. This approach is a little bit awkward as the list comprehension sits by itself. Let’s see what this looks like: # Remove Duplicates from a Python list using a List Comprehension 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. Similar to the method using for loops, you can also use Python list comprehensions to deduplicate a list. Remove Duplicates from a Python List Using a List Comprehension Want to learn more about Python for-loops? Check out my in-depth tutorial that takes your from beginner to advanced for-loops user! Want to watch a video instead? Check out my YouTube tutorial here. In the next section, you’ll learn how to deduplicate a list in Python using a list comprehension. If it didn’t, we appended the item to our list.We looped over each item in our duplicated list and checked if it existed in the deduplicated list.We instantiated a new, empty list to hold de-duplicated items.Let’s see what this looks like in Python: # Remove Duplicates from a Python list using a For Loop Using this method involves looping over each item in a list and seeing if it already exists in another list. The most naive implementation of removing duplicates from a Python list is to use a for loop method. Remove Duplicates from a Python List Using For Loops Use Pandas to Remove Duplicates from a Python List.
