- A file that data is written to is known as a(n)a. input file.b. output file.c. sequential access file.d. binary file.Use pseudocode to design a program that opens an output file with the external name my_name.dat, writes your name to the file, and then closes the file.Please use the Python program and adhere to the instructions; it should include two files. Program 1 - Write numbers to a file:1. Open an output file with the filename number_list.txt2. Use a loop to write the numbers 50 through 100 to thefile, and then close the file.Program 2 – Read numbers from a file:1. Open the file you just created.2. Read all the numbers from the file and display them.Terminate the loop by detecting end of file with a for loop(the second method we discussed).
- 2. Various file modes that opens file for writing and reading is definitely not А. арp,in B. ate,in C. in, out D. out, inThe following lines of code should open a file for writing (output). The name of the file is provided by the user. Fill in the blank with the correct function call to open the file: filename = input('Enter output file name: ') outfile = outfile.close()PYTHON without def function Problem Statement Assume an input file (called "numbers.txt") contains a number on each non-blank line of the file. Read in the file and then print out the sum of all the numbers read. The sum should be rounded up to 1 decimal. Sample Input (File numbers.txt) 1.0 2.0 3.25 4.0 Sample Output 10.3
- All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…PYTHON without def function Suppose an input file (called "scores.txt") contains a number on each non-blank line of the file. Read in the file and calculate/print the difference between the highest and lowest score. Sample Input (File scores.txt) 1.0 2.0 3.0 4.0 Sample Output 3.0Python program. Write a python program to get the number of lines of a code a file had. You should take file name from user
- what is input file stream ?This Python Lab 9 Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination file:…Question 24 Write a program that first reads in the name of an input file. The program will then read all the lines in the file and print them comma separated. Please do it ONLY in python Language please also include the screenshot of input and output.
