Python List Manipulation: Removing Duplicate Elements | Python | Tamil

In this code snippet, a list called 'duplicate_list' is defined with some elements. The list contains duplicate values like '5'. The code aims to remove duplicates and create a new list without them using sets and dictionaries in Python.

The code first prints the original list 'duplicate_list' using the print() function. Then, it utilizes the set() function to create a set called 'set_list' from 'duplicate_list'. A set is an unordered collection of unique elements, so any duplicate values in 'duplicate_list' will be automatically removed in 'set_list'.

Next, the code creates a dictionary called 'clean_dict' using 'dict.fromkeys(duplicate_list)'. The 'dict.fromkeys()' method creates a dictionary with the elements of 'duplicate_list' as keys and sets their corresponding values to None. This step is intended to remove duplicates as well since dictionaries cannot have duplicate keys.

After that, the code converts the keys of 'clean_dict' back to a list called 'clean_list'. This step effectively extracts the unique elements from 'duplicate_list' and stores them in 'clean_list'.
