Sorted List of 1994 Gas Prices
Note: This assignment can be done either as an enhancement to the program that you wrote for
In the student sample programs for this book, you will find a text file named 1994_Weekly_Gas_Averages.txt. The file contains the average gas price for each week in the year 1994, (There are 52 lines in the file. Line 1 contains the average price for week 1, line 2 contains the average price for week 2, and so forth.) Write a program that reads the gas prices from the file, and calculates the average gas price for each month. (To get the average price for a given month, calculate the average of the average weekly prices for that month.) Then, the program should create another file that lists the names of the months, along with each month’s average gas price, sorted from lowest to highest.

World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.) Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009. Tip: Read the contents of the WorldSeriesWinners.txt file into an ArrayList. When the user enters the name of a team, the program should step through the ArrayList, counting the number of times the selected team appears You only need to submit the…arrow_forwardThis assignment is in Python.

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.
