If you have downloaded the source code from the Computer Science Portal, you will find a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a company's valid charge account numbers. Each account number is a seven-digit number, such as 5658845. Write a PYTHON program that reads the contents of the file into a list. The program should then ask the user to enter a charge account number. The program should determine whether the number is valid by searching for it in the list. If the number is in the list, the program should display a message indicating the number is valid. If the number is not in the list, the program should display a message indicating the number is invalid. Don't forget to use try-except to prevent your program from crashing. Show your source code and output.
