Python's set.update(~) method updates a set in place, adding items from other iterables.

Parameters

1. iterable | iterable

The iterable whose elements we will add to the set.

Return value

None

Examples

Consider the following sets below:

a = {'dog', 'cat'}
b = {'sheep', 'dog'}
c ={'mouse', 'dog'}

#Add elements from sets b & c to set a
a.update(b, c)
print(a)
{'mouse', 'cat', 'dog', 'sheep'}

By definition, Sets do not allow duplicates values, hence 'dog' only appears once in set a.
