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
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:…
INSTRUCTION: C++ Language Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.
Inside Files (Use Python) Write a program that accepts an integer input, opens a file, and analyzes what and how many types of words are there in a line within the opened file. PROGRAM DESIGNThe program should be able to accept an integer input. This program should be able to open and read a file called tweets2.txt. The integer input represents the order of the line (from 1st to 5th line), within the tweets2.txt file. The program should be able to count how many stopwords, common words, unique words, and overall words are there in the line number input. In Natural Language Processing (NLP), stopwords are defined to be words with no meaning when left alone and with no context. For this activity, stopwords are words that are at most, 3 characters in length, with common words having more than 3 characters. Unique words are words, within the line, that don’t have any duplicates. Whereas overall words are the over all count of all words within the line. The program should also be able to…
answer in python Design and write a program that calculates and displays the number of minutes over the monthly contract minutes that a cell phone user incurred. The program should allow users to enter into a file minutes allowed in a month, minute used during a month and minutes over during a month for 12 months. The program reads the data from the file. The program validates the data as follows: - The minimum minutes allowed should be at least 200, but not greater than 800. Validate data accordingly. - The minutes used must be over 0. Validate data accordingly. Once correct data is read, the program should calculate the number of minutes over the minute allowed. If minutes were not over, print a message that they were not over the limit. If minutes were over, for every minute over, a .20 fee should be added to the monthly contract rate of 74.99. Be sure not to add the .20 fee for minutes 1 to the number of minutes allowed, but rather just minutes over. Display in a file the number…
In Python do the following: Writing to Files: write code to write to a file called ‘writefile.txt’To write in a file we first have to open the file. That is what the first line should do so that Pythoncreates a file object to represent the file, and give the object the name f (variable). We use this variableto refer to the file. To write to the file, use the print statement with the optional file argument thatspecifies the file to write to. When done writing, close the file to make sure all the changes are saved.Remember, if writefile.txt already exists, its contents will be overwritten.
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…

*Code in Python A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AM Enter the input file name: example.txt AM 3 I 3 SAM 3 The program should handle input files of varying length (lines).
in c++ input file is .txt Write a program that asks for the name of an input file. Then, read all the numbers in the file, and display the following information to the screen: count of numbers in the file sum of all numbers in the file average of all numbers in the file (to 2 decimal places) count of numbers in each range (100-199, 200-299, 300-399, etc.) The program should: display a hello message ask the user for an input file display the name of the input file validate the file opens correctly display statistical information as shown above display a goodbye message
Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file.
