Tuple items are ordered, immutable(unchangeable), and allow duplicate values.Tuples also allows indexing,slicing.Tuples are similar to list and can perform addition,multiplication Tuple packing and unpacking are features that allow you to group values into a tuple and extract them back into individual variables. Same functions can be used as list functions.The next() function returns the next item in an iterator.The '==' is known as the equality operator.Sets are used to store multiple items in a single variable.union(), intersection(), difference() and symmetric_difference() are different set operations.discard() and remove() methods.The tasks performed include set operations such as union, symmetric difference, difference, intersection and printing players played only in one match
