Sets in python.

Use add () function to add a single element. Whereas use update () function to add multiple elements to the set. add () is faster than update (). add () accepts immutable parameters only. Whereas accepts iterable sequences. add () accepts a single parameter, whereas update () can accept multiple sequences.
