Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…

linked list is an object that creates, references and manipulates node objects. In this assignment, you are asked to write a Python program to create a linked list and do a set of operations as follows:1. Create an empty linked list2. Create and insert a new node at the front of the linked list3. Insert a new node at the back of the linked list4. Insert a new node at a specified position in the linked list5. Get a copy of the data in the node at the front of the linked list6. Get a copy of the data in the node at a specified position in the linked list7. Remove the node at the front of the linked list8. Remove the node at the back of the linked list9. Remove the node at a specified position in the linked list10.Traverse the list to display all the data in the nodes of the linked list11.Check whether the linked list is empty12.Check whether the linked list is full13.Find a node of the linked list that contains a specified data itemThese operations can be implemented as methods in a…
