Transcribed Image Text:ΡYTHON
Write a program that first reads in the name of an
input file, followed by two strings representing the
lower and upper bounds of a search range. The file
should be read using the file.readlines() method.
The input file contains a list of alphabetical, ten-
letter strings, each on a separate line. Your program
should output all strings from the list that are
within that range (inclusive of the bounds).
Ex: If the input is:
input1.txt ammoniated millennium
and the contents of input1.txt are:
aspiration classified federation graduation
millennium philosophy quadratics transcript
wilderness zoologists
the output is:
aspiration classified federation graduation
millennium

File cart.txt contains shopping cart type data from golfsmith.com representing the gifts you have purchased for your dad for this past Fathers Day. Good for you. You have been very generous! The first item in each row of the file is the part number, the second the quantity, the third the price and the fourth the description. Your program will read the file line by line and compute the total cost of all of the items in the list. You will then display a message that looks like this, assuming the cost of each item adds up to 168.42: Here's what your output should look like: The total price for the awesome Fathers Day gifts you bought is $168.42. The shopping cart can be found here: cart.txt.

For each Student, the calculateAvg function receives a list containing the 5 values and returns another list containing all the values in the original list plus the average score of the quizzes for each student. This information will be written in an output file as shown below. Also, you must include the class average at the end. Which includes all the students in the list.

- Java Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time.

- In Python: I've received a few errors, what could I be doing wrong? Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.
