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
