In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs. Be sure to downloadand place the appropriate text files in the same directory as your python file. You only need to submityour python file.Partial Dictionary: {d : a, e: f, h : b, l : p, l : e, o : j, r: m, w: i}originalMessage = “hello world” → encryptedMessage = “bfeej ijmea” Part 1 - Encrypt a Message: You will write 2 functions to build a dictionary and encrypt a messageFunction buildCypher() → dict:This function is to build a dictionary that can be used to create a random substitution cypher.

Complete the Python program to create a Horse table, insert one row, and display the row. The main program calls four functions: create_connection() creates a connection to the database. create_table() creates the Horse table. insert_horse() inserts one row into Horse. select_all_horses() outputs all Horse rows. Complete all four functions. Function parameters are described in the template. Do not modify the main program. The Horse table should have five columns, with the following names, data types, constraints, and values: Name Data type Constraints Value Id integer primary key, not null 1 Name text   'Babe' Breed text   'Quarter horse' Height double   15.3 BirthDate text   '2015-02-10' The program output should be: All horses: (1, 'Babe', 'Quarter Horse', 15.3, '2015-02-10')

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py  Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list:     [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as:     ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.  In this small example, we don’t achieve much of a savings (and indeed the…

Assume a Dictionary structure has been defined that associates letter grades to their respective integer "quality point" values used for calculating a student's grade point average. The name of the structure is gradePoints. Write a statement to retrieve the quality point value for a letter grade of "C". Store the retrieved value in a variable named "qPoints".

Seq is a sequence object that can be imported from Biopython using the following statement: from Bio.Seq import Seq If my_seq is a Seq object, what is the correct Biopython code to print the reverse complement of my_seq? Hint. Use the built-in function help you find out the methods of the Seq object. print('reverse complement is %s' % complement(my_seq.reverse())) print('reverse complement is %s' % my_seq.reverse()) print('reverse complement is %s' % my_seq.reverse_complement()) print('reverse complement is %s' % reverse(my_seq.complement()))

Python decorators can be used in Django in order to avoid duplication of code in view functions. For instance, consider the following definition of a decorator that is then applied to a view function. This code has three bugs: 01: def fetch_author (view_func) : 02: 03: 04: 05: 06: 07: 08: def wrapper (request, *args, **kwargs) : return view_func 09: 10: @fetch_author 11: def books_new (request) : 12: 13: 14: 15: 16: 17: } books = Book.objects.filter (authors _in= [author], year_ _gte="2015") context = { try: author = Author.objects.get (id-request. GET ["author_id"]) view_func (request, author, *args, **kwargs) except Author. Does NotExist: return bad_request (request, Author.DoesNotExist) Line 02 Line 05 Line 08 return render (request, "books-recent.html", context) Line 11 Identify the three lines which contain the three bugs: Line 12 Line 17 "title" : "New books", "books" books,
