Transcribed Image Text:Suppose that the file named Gradedata.txt in disk D:\ contains the
following data about student : The student name, four grades, and the
year of birth respectively (for example :Ahmad 90 80 66 80 2002). Your
program should read the name of the student, the four grades, and the
year of birth from the file, then calculate the average, and then print the
student name, grades, and average on the computer screen. The
program should also find the age of the student and whether his/her year
of birth is a leap year or not and print that on the screen. »

- In Python: The Broadway dataset contains data for Broadway shows' Capacity (percentage of the theatre filled) and Gross Potential (maximum amount that can be earned) for multiple shows in a specific month and year. Given a CSV file name read from user input, write a program that performs the following tasks: Read in the CSV file as a dataframe. Insert a new column labelled "Size" at the end of the dataframe. The "Size" column contains values in column "Gross Potential" divided by 2. Output the dataframe using the print() function. Create a scatter plot of "Gross Potential" vs "Capacity" with the following marker styling parameters: markers: 'x' color: orange size: values in column "Size" Add the x-label ("Capacity", fontsize = 10), y-label ("Gross Potential", fontsize = 10), and title ("Gross Potential vs Capacity", fontsize = 16) to the figure. Add gridlines to the figure using '--' as linestyle. Save the figure as output_fig.png.

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. Right click on the link and save the file to the folder where you have your Python files.arrow_forward
- PYTHON: I need to get the avg statement out of the loop so that the output prints correctly. Any suggestions. Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam…arrow_forwardWrite a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below: o o D D0 1 2 3 4 5 6 7 8 9 10arrow_forwardPython Create a program that reads the file (create a paragraph in a file). It should analyze each character of the file. For output, it should produce a well-formatted table indicating: The total number of printable characters The total number of capital letters The total number of lowercase letters The total number of numbers The total number of sentences (which end in a period) The total number of paragraphs (which end in a newline) Since the lab is an exercise in strings, you must use at least TWO different string methods to required information. And each stastic will need its own function.arrow_forward
- For this assignment, you will write a Python program that uses a file named scores.txt to store sets of bowling scores for different dates. scores.txt should store the data so that each line has a month, day, and the scores the user earned on that date. As an example, scores.txt might look something like this: January 15 200 300 126 200 250April 20 125 100 May 17 300 100 215 The very first time your program starts, scores.txt should not exist (i.e. create it with Python code the first time the program runs). In your main function, continuously give the user the following five options: Quit the program. View all Scores. If the user selects this option, call a function named view_scores. This function should print the scores in a nicely formatted manner. For example: "On January 15, you scored 200, 300, and 126", etc.. Add a Score. If the user selects this option, call a function named add_score. This function should ask the user for a month, day, and as many scores as they want to…arrow_forwardJava 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.

- here is a text file containing the details of several invoices details. Each invoice uses 3 lines of the file. The first of the three lines is a string giving the date of the invoice, for example “1/5/2021” or “2/6/2021”. The second of the three lines contains double giving the amount, the third line is boolean indicating whether it is paid or not. However, the very first line of the file is an integer number, which says how many invoices are given in the file in the lines which follow it (i.e. how many records will follow). Text file example for two vehicles “invoices.txt” 2 1/5/2021 50.0 true 2/6/2021 20.0 false Write code for a method named processTextFile() which will open the file named ‘invoices.txt’, from which it will read the data of invoices. It will create Invoice objects using this data by calling the constructor that takes the parameters (date, amount, paid) , placing them into an ArrayList invoiceList.arrow_forward The fields below repeat for each customer: o Customer name (String)o Customer ID (numeric integer) o Bill balance (numeric)o EmailAddress (String)o Tax liability (numeric or String) The customers served by the office supply store are of two types: tax-exempt or non-tax- exempt.
