Program 5: Word Frequencies (Concordance) Use a text editor to create a text file (ex: myPaper.txt) It should contain at least 2 paragraphs with around 200 or more words. Write a Python program (HW19.py) that asks the user to provide the name of the text file. Be SURE to check that it exists!Do NOT hard-code the name of the file! Use the entry provided by the user! read from the text file NOTE: (write your program so that it ONLY works if it reads from the file specified by the user). Your program will produce a dictionary of words with the number of times each occurs. It maps a word to the number of times the word occurs Key: a word Value: the number of times the word occurs in the text. The report should be an ALPHABETIZED output table, listing the word and the number of occurrences. NOTES: The input sequence can be words, numbers or any other immutable Python object, suitable for adict Ignore case – apple is the same as Apple is the same as APPLE, etc. Discard all…
Using matplotlib, a Python program that reads the contents of the file see attached then plots the data as either a line graph or a bar chart. Be sure to display meaningful labels along the X and Y axes, as well as the tick marks. The file contains the average gas price for each week in the year 1994. (There are 52 lines in the file.)

Below this question is a generated text representing a DNA sequence. The first line starts with '>' and is a comment, and the lines after that hold the sequence. The sequence has letters 'A', 'C', 'T', and 'G'. In your program (written in python) for this question, read the sequence using the statements: f = open('kdpF.txt') # opens a file for reading line = f.readline() # reads a single line print(line) seq = ''for line in f : # reading the rest of the lines seq = seq + lineseq = seq.replace('\n', '') # removing the newline characters seq = seq.upper() print(seq) def gcContent(sequence) : # You do the rest pass Also write a function gcContent(sequence), which returns the percent of the sequence which is either 'G' or 'C'. Use your function on the input sequence and print the results. generated text DNA sequence: >200 bp region of the chromosome of E. coli, containing gene kdpF, shortest…
Each student will have to build a bookstore management system for adding, deleting, or searching for books in the store. Each book will have a title (string), bin number (four digit integer), and a price (double). When the program starts, it will load existing book information from a text file and when the program exits, it will save all changes made while running the program to that same file.After the book information is loaded from the file ( In this phase all you need to do is just print a message that the book information is loaded, but you don’t really open any files or load anything) , the program will display the following main menu to the user:Please Select an Operation (1-4):1- Add a Book2- Remove a Book3- Search for a Book4- Exit System2This menu will keep showing after each time a user selects an operation and that operation is performed. When the user selects operation 4 (exit system), the program will load all changes (updates) to the file ( In this phase all you need to…
I have the basis of a program that works as an inventory, it reads the contents of a file and displays them and their quantity in three places, and I need to add in a warning option that will alert that in any of the places the amount of product is below 10. Lab = This lab is to to add another option for the user to print warnings of any inventory running low. More specifically:- Add another option to the menu, called W for Warning- Look at all items, in all locations. If an item has less than 10 left, print out on one line the item name,location, and quantity. Pictures included are: 1. How the program currently runs 2.
