Python's “in” set operator

Question

I\'m a little confused about the python in operator for sets.

If I have a set s and some instance b, is it true that b i

Answer 1

Yes it can mean so, or it can be a simple iterator. For example: Example as iterator:

a=set(['1','2','3'])
for x in a:
 print ('This set contains the value ' + x)

Similarly as a check:

a=set('ILovePython')
if 'I' in a:
 print ('There is an "I" in here')
