assume the file data.dat contains a sequence of binary data. write a program that does the following:
displays the first 5 bytes stored in the file. each byte should be displayed on a separate line.
starting with byte 0, displays every even-numbered byte in the file. (in other words, display byte 0, byte 2, byte 4, and so on.) each byte should be displayed on a separate line.
starting with byte 1, displays every odd-numbered byte in the file. (in other words, display byte 1, byte 3, byte 5, and so on.) each byte should be displayed on a separate line.
displays the last 5 bytes stored in the file, in reverse order. (display the last byte, then the next-to-last byte, and so on.) each byte should be displayed on a separate line.
handle exceptions in the following manner:
if a filenotfoundexception is thrown, the program should display the string "file error".
if an eofexception is thrown, the program should display the string "eof error".
if any other exception is thrown, the program should display the string "error".
the name of your program class must be datadisplay.

Assume the file data.dat contains a sequence of binary data. Write a
program that does the following:
• Displays the first 5 bytes stored in the file. Each byte should be displayed
on a separate line.
Starting with byte 0, displays every even-numbered byte in the file. (In
other words, display byte 0, byte 2, byte 4, and so on.) Each byte should
be displayed on a separate line.
• Starting with byte 1, displays every odd-numbered byte in the file. (In
other words, display byte 1, byte 3, byte 5, and so on.) Each byte should
be displayed on a separate line.
Displays the last 5 bytes stored in the file, in reverse order. (Display the
last byte, then the next-to-last byte, and so on.) Each byte should be
displayed on a separate line.

- im usually using python Write a program named filemaker.py that will be used to store the first name and age of some friends in a text file named friends.txt. The program must use a while loop that prompts the user to enter the first name and age of each friend. Each of these entries should be written to its own line in the text file (2 lines of data per friend). The while loop should repeat until the user presses Enter (Return on a Mac) for the name. Then, the file should be closed and a message should be displayed. See Sample Output.SAMPLE OUTPUT Enter first name of friend or Enter to quit DennyEnter age (integer) of this friend 24Enter first name of friend or Enter to quit PennyEnter age (integer) of this friend 28Enter first name of friend or Enter to quit LennyEnter age (integer) of this friend 20Enter first name of friend or Enter to quit JennyEnter age (integer) of this friend 24Enter first name of friend or Enter to quit File was createdarrow_forwardprogram - python Write a program using a for loop that creates a file and adds even numbers the integers 1 through 20 loop to the file. Name the file numbers. txt. Then perform the following on the file: Read all of the numbers stored in the file and calculate their total. Display all the numbers in the file and the calculated total Using a for loop add the following numbers to the file 21 through 30 Delete the following numbers from the file 24, 25, 26 (using a temp.txt file) Change the number 10 to 50 (using a temp.txt file) Hint: if you want to use ! Use module os that is part of Python to manipulate files.: import os. You can use functions that come with “os” module. Functions remove and rename can be used as explained below. rename(old_name,new_name):This function renames the old_name to new_name). remove(filename)method in Python is used to remove or delete a file.arrow_forwardChapter 4. PC #6. File Letter Counter (page 264) Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Class name: FileLetterCounter Hints: Hint 1. To read a single character from the keyboard, you need to read a full line and then take the first character in position 0. Hint 2. To count the occurrences of a given characters in a file you need to read the file line-by-line using a while loop, then for each line check all characters in all positions and increment the character counter for each occurrence. This will require to have a for-loop nested inside the while-loop.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_forwardGiven the following, write a code SEGMENT that does the following: Creates a string variable to store a file name (to be entered by the user) Requests the input file name from the user and stores the name in a variable Opens the input file using the entered file name Tests the STATE of the file open. If the file does not open, output a message to the user exit the program Be sure to: Include the necessary header files Declare necessary variablesarrow_forwardQI: Write a program to calculate the average of four integer score, and find the grade for 7 students. The program should do the following: 1. Read the first, second name and the four score of the 7 student from the file (E:lexam.txt), 2. Calculate the average and find the grade of the average by using the if and if else. 3. Save the first, second name, average and the grade for each student in file (E:grade.txt).
