The add() method takes a single argument, which can be any datatype, and adds the given value to the set.
Sets are bags of unique values. If you try to add a value that already exists in the set, it will do nothing
The update() method takes one argument, a set, and adds all its members to the original set
The pop() method removes a single value from a set and returns the value. However, since sets are unordered, there is no “last” value in a set, so there is no way to control which value gets removed
Attempting to pop a value from an empty set will raise a KeyError exception.
Like lists and sets, the len() function gives you the number of keys in a dictionary.
