Python videos | Python Part 10 - Sets

Posted by Andy Brown on 18 October 2021

Python Part 10 - Sets

Sets in Python provide a beautifully elegant way to remove duplicates from a list and to compare the contents of two lists, as this tutorial hopefully will prove to you!

See our full range of Python training resources, or test your knowledge of Python with one of our Python skills assessment tests.

This video has the following accompanying files:

File name	Type	Description
Working with sets.py	Python code	Code for set operations
Eg 1 - remove duplicates.py	Python code	Removing duplicates from a shopping list
Shopping list.txt	Text file	The shopping list itself
Eg 2 - counting letters and words.py	Python code	Counting unique letters and words in quotation
Eg 3 - promotions and relegations.py	Python code	Comparing premier leagues for 2 seasons
PL 20-21.txt	Text file	Premier league end 2020-21
PL 21-22.txt	Text file	Premier league start 2021-22

Click to download a zipped copy of the above files.

After watching this video, you may like to test your understanding by doing one or more of the following exercises:

Exercise	Level

You can also download the answers to each exercise from the links above.
