Remove Duplicates from a List of Tuples of Different Length with Python

To remove the duplicates from a list in Python, we can use the built-in function set(), and the specialty of the set() method is that it returns distinct elements. 

To remove duplicates from the list of tuples, the loop, any method, and the enumerate method can be used in Python. A list can store heterogeneous values, that is, data of any data type like integer, string, floating points, etc. We can find where the duplicates are present in the list of tuples by iterating through the tuples list, and for each tuple, we must check if it exists in the dictionary. If it does, it means that the tuple is a duplicate, and we can add it to a separate list of duplicate tuples, and if it does not, we can add it to the dictionary as a key with the value of 1. The distinct keyword is used for duplicate tuples, and to ensure that duplicates are not removed, we can use all keywords. To remove duplicates regardless of order, we need to sort the list's tuples, and then check for duplicate values to remove them and print the values; Python provides multiple methods to perform a task. 

The quick way to remove duplicates from a list in Python: 

• List Comprehension. 
• Using Dictionary Keys. 
• List count() function. 
• Using the set() built-in method. 
• Using a temporary list and looping.
