Create a file called contacts.py, implement a program that prompts the user to select a choice between these 5 options. Add contact (1), Delete Contact (2) Save Contact(3), show all contact (4), exit program (5). Contact info should be saved in a separate read/write file. If user inputs number (1) on the keyboard, then prompt them to input the name and number of the contact. If user selects (2), delete all contacts or show an error if there are no contacts saved to file. If user inputs (3) save the contact and loop the choice of the 5 options until user inputs (5) to exit. If user inputs (4) print out the saved contacts to the screen neatly, Name, Number(newline). if user inputs 5 then exit the program. If the user inputs a number not shown then give an error message and ask them to input a valid number.  Please code in python, preferably using case statements to complete

here is a text file containing the details of several invoices details. Each invoice uses 3 lines of the file. The first of the three lines is a string giving the date of the invoice, for example “1/5/2021” or “2/6/2021”. The second of the three lines contains double giving the amount, the third line is boolean indicating whether it is paid or not. However, the very first line of the file is an integer number, which says how many invoices are given in the file in the lines which follow it (i.e. how many records will follow). Text file example for two vehicles “invoices.txt” 2 1/5/2021 50.0 true 2/6/2021 20.0 false Write code for a method named processTextFile() which will open the file named ‘invoices.txt’, from which it will read the data of invoices. It will create Invoice objects using this data by calling the constructor that takes the parameters (date, amount, paid) , placing them into an ArrayList invoiceList.

Write a program that reads student's IDs and exam scores (type int) for a particular exam in a course from each line of an input file (the input file is included). You need to compute the average of these scores and assign grades to each student according to the following regulation: If a student's score is within 10 points (above or below) of the average, assign a grade of satisfactory. If a student's score is more than 10 points above average, the grade will be outstanding. If a student's score is more than 10 points below the average, the grade will be unsatisfactory. The output of your program should consist of a three-column table that shows each ID, score, and corresponding grade. A sample output is shown below. ID SOLS SENTO 0 1 2 3 4 8 9 Score 75 99 66 43 87 65 82 91 84 76 Grade Satisfactory Outstanding Unsatisfactory Unsatisfactory Outstanding Unsatisfactory Satisfactory Outstanding Satisfactory Satisfactory Write necessary functions and put them in a module to process this…

Write a program that reads data from a file containing integers that ends with -999.   Output the numbers that are divisible by 7   Output the numbers that are divisible by 11  Output the numbers that are not divisible by 7 or 11

Write a program that queries information from three files(given to you). The first file contains the names and telephone numbers of a group of people. The second file contains the names and Social Security numbers of a group of people. The third file contains the names and annual income of a group of people. The groups of people should overlap. Your program should ask the user for a telephone number and then print the name, Social Security number, and annual income, if it can determine that information. Sample run1: Enter the phone number (7 digits, with a dash): 555-1234 555-1234 is associated with Bob Bob's SSN is 000300021 Bob's salary is 55000 Sample run2: Enter the phone number (7 digits, with a dash): 675-4566 Couldn't find a name associated with that number. Sample run3: Enter the phone number (7 digits, with a dash): 000-2345 000-2345 is associated with John John's SSN is 000000004 John's salary is 65000 python language

Write a complete java program that: asks the user for a file name tests whether the file exists and tells the user  if it does exist asks the user whether it should be deleted.  Either delete or do not delete the file based on the user input. If they don't delete, ask them if they would like to write to the file If they want to write, ask what they want to write to the file and write it.  Make sure to provide plenty of console output dialog specifying what status/actions are taken at each step.

Write a program that asks the user for a file name and a string to search for. The program should search the file for every occurrence of a specified string. When the string is found, the line that contains it should be displayed. After all the occurrences have been located, the program should report the number of times the string appeared in the file.
