What is wrong with the following code snippet that is supposed to print the contents of the file twice? infile open("input.txt", "r") %3D for sentence in infile : print(sentence) for sentence in infile : print(sentence) Select one: O A run-time error occurs because the file does not exist O The program cannot use the variable sentence twice O Python cannot iterate over the file twice without closing and reopening the file O Nothing, the code prints the contents two times

Need a different function in python that reads the data file and round the code below (see attached image) def calculateTotal(Name, Item, Price, Quantity):    total = round(Price * Quantity,2)    return total

can you do it python

Write a program in C++ that allows the user to create files of random data. They should be offered a menu of possibilities: 1) create random Whole number data file 2) create random Decimal number data file 3) create random Character data file 4) Quit program

What does the following python code do? f = open("sample.txt", "w") Choose all that apply.    Select 2 correct answer(s) a. writes "w" to the file called sample.txt  b. if the file sample.txt exists, deletes everything in it c. closes a file called sample.txt d. If the file called sample.txt exists, it writes at the bottom of the file e. opens a file called sample.txt for appending f. if the file sample.txt does not exist, it creates the file and opens it for writing g. reads the file called sample.txt starting from the top h. opens a file called sample.txt for reading

Python programming help  I need help of question 1 to read a file from persons.txt   Write a program that takes a person’s details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. You should write three person’s to the file. The program terminates on entering any key by the user, except on (Y or y) key.  Sample output of the first run of the program is shown below:              Enter name: JohnEnter age: 20Enter city: SydneyData saved:  John 20 SydneyPress (Y or y) to add another person, or any key to exit    Question 1) Write a program that read a file (persons.txt) from previous question given on the top of this question, and shows all the records/lines from the file as a nicely formatted report with a header as shown:    Name                   Age                      City   +---------------------+--------------------+--------------

USING C++ PLEASE CREATE THREE FILES! IntCollection.h (or IntCollection.hpp): class definition IntCollection.cpp: class implementation main.cpp, including sample output and your answer to question 6 at the bottom. : main program to run the code The following code creates an IntCollection object named ‘c’. It adds seven integers to ‘c’, then uses a for loop to display the seven integers: int main() { IntCollection c; c.add(45); c.add(-210); c.add(77); c.add(2); c.add(-21); c.add(42); c.add(7); for (int i = 0; i < c.getSize(); i++) { cout << c.get(i) << endl; } } For this assignment you will add a copy constructor, a destructor, and three overloaded operators to the IntCollection class. In the design diagram below, the black member functions represent code that has already been implemented. You will be implementing the green items. Each item that you will be adding to the class is described below the diagram. private: int size // the number of ints currently stored in…

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…

Answer the given question with a proper explanation and step-by-step solution.  1- 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, then closes the file.
