The simplest way to remove duplicates in Python is to use the set data type. A set is an unordered collection of unique elements. Therefore, by converting a list to a set, we can easily remove all duplicates. Here's an example: my_list = [1, 2, 2, 3, 4, 4, 5] my_set = se...
In this Python tutorial, we explored 4 different techniques to remove duplicates from a list while preserving order. Each method has its use cases, performance considerations, and syntax ease. Depending on the data type and requirements, you can choose the most suitable method. Happy Learning !!
