Python: I am trying to write a simple GUI based program with two input fields “Directory/filename” and “word” next to each other and one output text field below. Using recursion the program should go through all the files and folders searching for the entered word. If a match is found the path to the file should be printed in the text field + the content of line the word is found in . It should also print how many folders and files has been searched and how many times the word was found. Any ideas?

- Write a C# program FileComparison that compares two files. Two files have been provided for you, Quote.txt and Quote.docx, both containing movie quotes and are located in the /root/sandbox/ directory Next write the file comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file’s size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME); size = fileInfo.Length; Your program's output should look like the following: The size of the Word file is FILE_SIZE and the size of the Notepad file is FILE_SIZE The Notepad file is x% of the size of the Word filearrow_forwardWhen it loads, the list of car objects should be created by reading from the above file.

Write a program that reads a file named input.txt and writes a file that contains the same contents, but is named output.txt. The input file will contain more than one line when I test this and so should your output file. Do not use a path name when opening these files. This means the files should be located in the top level folder of the project. This would be the folder that contains the src folder, probably named FileCopy depending on what name you gave the project. Do not use a copy method that is supplied by Java. Your program must read the file line by line and write the file itself. I will test it with a file, input.txt do not write to input.txt* Your class name must be FileCopy.arrow_forward

- using visual studio and the C# please dont copy the previous answered questions because the solution is incorrect In the Chap07 folder of the Student Sample Programs, you will find a file named ChargeAccounts.txt. The file contains a list of a company’s valid charge account numbers. There are a total of 18 charge account numbers in the file, and each one is a 7-digit number, such as 5658845. Create an application that reads the contents of the file into an array or a List. The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List, the program should display a message indicating the number is valid. If the number is not in the array or List, the program should display a message indicating the number is invalidarrow_forwardCreate a file in your project named employees.txt with the following data (you can simply create the file by hand rather than with Python code): 123 Bob Smith345 Anne Jones256 Carol Lee845 Steve Robert Anderson132 Jill Thompson From your program's main function, give the user the following options: lookup a name based on ID number, lookup an ID number based on name, and quit the program. OPTION 1: The user chooses to lookup a name based on ID number: Use a try/except and ask the user to enter an integer. If they don't enter an integer, print an error message. If they do enter an integer, call a function named lookup_employee which takes the id as a parameter. If an employee with the given id number is found, return the name.
