Working with Sets of Python for Network Engineers

This post is about the most common / useful things we do with Sets in Python.

It is better if you see this as the Sets which we worked with Venn Diagrams in old day schools. This is the same thing..

 

Adding & Removing

To add an item to a Set, we can use add() function and we can use remove() to remove an item.

Note that we can use pop() function but it should be used with out a value when dealing with Sets and it will remove a random item from the Set.

Union

We can merge 2 sets into 1 with all the values. We can assign a new variable and assign the all values to new Set of all values.

Intersection

This gives the items which are common to both sets.

Difference

This is just the minus the 2nd Set from the 1st Set.

 

This can also be achieved by just arithmetic (-)
