Create a python program that reads the student information from a tab separated values (tsv) file. The python program then must creates a text file that will records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midtrm1 score, Midtrm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfoScore.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

Create a source code text file and save it as named text.txt. Write a program that reads the file's contents and determines the following:
- The number of uppercase letters in the file.
- The number of lowercase letters in the file.
- The number of digits in the file.
- The number of whitespace characters in the file.
* Note: Please be sure to use the Python program when creating the program. Thanks!

At a local farmers market, you and a buddy sell your agricultural products over the course of four weekends (on both Saturday and Sunday). For each day you were selling, create a software that asks your buddy how much money you made. Use a spreadsheet to keep track of this data. Create a new text file named yearly farmers market sales.txt and use a loop to tally up all of the sales for the year. Report the worst sales days. Report the top sales days. Report the average number of sales per location.
Make sure you have a main function and a calculating function in place at all times. The "storage" of your output may be handled in the main function.

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.

In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.

It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w').
