This function can enumerate both sequences like sets, tuples, strings and lists as well as mappings like dictionaries The enumerate function returns a collection of tuples. Each tuples is a pair comprising of the index and the value.

Describe how tuples can be useful with loops over lists and dictionaries, and give Python code examples. Create your own code examples. Do not copy them from the textbook or any other source. Your descriptions and examples should include the following: the zip function, the enumerate function, and the items method.

Given two lists, create a function that returns a list of all of the elements in both lists, with no duplicates. Aim: The aim of this activity is to implement an algorithm that returns the union of elements in a collection. Although working with sets is quick and easy in Python, sometimes we might want to find the union between two lists. Create a function called unite_lists, which uses a loop to go through both lists and return common elements. Do not use the built-in set function. Steps for Completion: 1. Define a function named unite_lists. 2. Use a for statement to iterate through the two lists, while finding the common elements in both lists without duplicates. Snippet 6.109 shows an example output: >>> unite_lists([2,4,6,8],[3,6,9,12]) [2, 4, 6, 8, 3, 9, 12]
