Append values to a set in Python

Question

I have a set like this:

keep = set(generic_drugs_mapping[drug] for drug in drug_input)

How do I add values [0,1,2,3,4,5,6,7,8,9,10]

Answer 1

The way I like to do this is to convert both the original set and the values I'd like to add into lists, add them, and then convert them back into a set, like this:

setMenu = {"Eggs", "Bacon"}
print(setMenu)
> {'Bacon', 'Eggs'}
setMenu = set(list(setMenu) + list({"Spam"}))
print(setMenu)
> {'Bacon', 'Spam', 'Eggs'}
setAdditions = {"Lobster", "Sausage"}
setMenu = set(list(setMenu) + list(setAdditions))
print(setMenu)
> {'Lobster', 'Spam', 'Eggs', 'Sausage', 'Bacon'}

This way I can also easily add multiple sets using the same logic, which gets me an TypeError: unhashable type: 'set' if I try doing it with the .update() method.
