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] into this set?

Answer 1

First, use : 

keep.update(yourvaluesequence)

Like, keep.update(xrange(11) specifically for your example. In case you want to produce the values in a loop for some other reason, then you can, by using:

for ...whatever...:

  onemorevalue = ...whatever...

  keep.add(onemorevalue)
