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]
into this set?

Define a set
a = set()
Use add
to append single values
a.add(1)
a.add(2)
Use update
to add elements from tuples, sets, lists or frozen-sets
a.update([3, 4])
>>> print(a)
{1, 2, 3, 4}
Note: Since set elements must be hashable, and lists are considered mutable, you cannot add
a list to a set. You also cannot add
other sets to a set. You can however, add the elements from lists and sets as demonstrated with the .update
method.
