- A student wants to write into a file called myfile, without deleting its existing content. Which one of the following functions should he or she use? f = open('myfile', 'r') f = open('myfile', 'w+b') f = open('myfile', '+') f = open('myfile', 'a')Design an application for the ABC Company that will process inventory from a file called ABC_Inventory.txt (attached to this assignment). The file contains Item ID, Description and list price stored on a separate line in the file. The program should display the contents of each record and then calculate and display the average list price. it is important that this is done in Thonny for python w1. Write a program that asks the user for the name of a file. The program should display only the 3 lines of the file's contents. If the file contains less than 3 lines, it should display the file's entire contents. Use the file: lorem_ipsum.txt to test your program. Comment your source code and describe your code to someone who may be viewing it for the first time. PLACE SCREENSHOTS OF THE PYTHON CODE AND ALL I/O BELOW. Please use Python Programming
- Assume that there is a data file named as “data.txt”. This data file contains integer values in multiple lines, as shown below. You are asked to write statements in the main() method to open the file, read and print out the total of all the values (should be 55). Place your code into try-catch block so that the FileNotFoundException will be caught and an error message will be printed if no such file exists. data.txt 1 2 3 4 5 6 7 8 9 10 import java.util.*; import java.io.*; public class ReadAndPrint { pubilc static void main() { // your code goes here }Python programming only NEED HELP MAKING FLOWCHART FOR PROGRAM CODE IS ALREADY CORRECT JUST NEED FLOWCHART (CODE INCLUDED): My Code: def read_and_display_random_numbers(file_path):total = 0count = 0with open(file_path, 'r') as file:for line in file:random_number = int(line.strip())total += random_numbercount += 1print(random_number)return total, countif __name__ == "__main__":try:file_path = input("Enter the file path to read random numbers from: ").strip()if not file_path:raise ValueError("File path cannot be empty.")total, count = read_and_display_random_numbers(file_path)print(f"\nTotal of the numbers: {total}")print(f"Number of random numbers read from the file: {count}")except ValueError as ve:print(f"Error: {ve}")except Exception as e:print(f"An error occurred: {e}")In Python, Create a program that will write 100 integers created randomly in a file. The integers will be separated by a space in the file. Read the data back from the file, and display the sorted data. The program should prompt the user to enter a file name. Utilize the following function headers for this problem: Main() WriteNumbers(filename) ReadNumbers(filename) The main function will first prompt the user to enter the filename. Then the main function calls WriteNumbers-then ReadNumbers. The WriteNumbers function opens an output file and writes 100 random numbers as long a large string text. Do not use lists for this problem- please just write a random number followed by a space 100 times. The ReadNumbers function will then read the text file and display the numbers sorted. In order to sort the numbers, read the big string and then split it into a list. Now convert them into integers by using list comprehension and then sort the list. Loop through the list and print each…
- In Python, which of the following opens read_it.txt for writing or reading data text_file variable. a. text_file = open("read_it.txt", "wr") b. text_file = open("read_it.txt", "rw") c. text_file = open("read_it.txt", "aw") d. text_file = open("read_it.txt", "w+") which one is correct?step 1: Write a python program that will ask the user for their grocery list, one item at a time, and will write it to a file called groceries.txt. The program should create a new file called groceries.txt that will contain all of the user’s groceries when opened. Step 2: Modify the python program that creates a groceries.txt file so that if the user’s favourite fruit is not on the list, the program will append it to the end of groceries.txt file.2. This involves a .txt file with one thousand rows of random numbers (between 1-1000) Using Python, create a program to perform this task, with 3 methods of doing this: Read the entire contents of file1.txt into memory, then process each row. Read one row of file1.txt at a time and process it. Split file1.txt into 2 parts and read each part into memory separately.
- You have more flexibility to implement your own function names and logic in these programs. The data files you need for this assignment can obtained from:Right-click and "Save Link As..." HUGO_genes.txt (Links to an external site.) chr21_genes.txt (Links to an external site.) Create an output directory inside your assignment4 directory called "OUTPUT" for result files, so that they will not mix with your programs. Output from your programs will be here! Your program must implement command line options for the infiles it must open, but for testing purposes it should run by default, so if no command line option is passed at the command line, the program will still run. This will help in the grading of your program. Create a Python Module called called my_io.py - You can use the same code from assignment 3's solution. Put this my_io.py Module in a subdirectory named assignment4 inside your assignment4 top-level directory (see the tree below, and see Lecture 7 on how to implement a…A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write a program that creates the following three files: dataplus.txt dataminus.txt zeros.txt The program should read each line of the data.txt file and perform the following: If the line contains a positive number, that number should be written to the dataplus.txt file. If the line contains a negative number, that number should be written to the dataminus.txt file. If the line contains the value 0, do not write the value to a file. Instead, keep a count of the number of times 0 is read from the data.txt file. After all the lines have been read from the data.txt file, the program should write the count of zeros to the zeros.txt file.Write a program that creates the following three files; dataplus.txt dataminus.txt zeros.txt The program should read each line of the data.txt file and perform the following; If the line contains a positive number, that number should be written to the dataplus.txt file If the line contains a negative number, that number should be written to the dataminus.txt file If the line contains the value 0, do not write the value to a file. Instead, keep a count of the number of times 0 is read from the data.txt file After all the lines have been read from the data.txt file, the program should write the count of zeros to the zeros.txt file.
