Write a python code to build a system that helps with customer management by providing the following services:

A clear easy to use main menu which should include the following options

Audit Report: It lists the basic information on which the program works. Display the details of all the Orbital Services and details of all the Customers.

Customer Letter: It can automatically write a friendly letter to customers with customized name and address and launch details for a given year.

The letter has quite specific formatting requirements on the This years and Future services lines specifically:

Based on date entered services from past years should not be shown.

There could be 1 or 2 lines of this years services

There could be 1 or 2 lines of future services

If there are no services, this year it should say No service this year (note None is not ok)

If there are no future services, it should say No future services (note None is not ok)

Note: Also, that input errors should be detected (e.g., a company code of FRED or a year of 29919)

Commission Report: It produces a commission report showing the commission that a customer generates for the currently scheduled launches.

If the 1st stage is recovery by sea, then an additional $165,000 cost of recovery is taken into consideration before Sales Commissions are applied. This is a way of encouraging salespersons to sell the cheaper land recovery services hence it is subtracted before commission is calculated.

Sample Commission calculation for ESAA ORB 1. (Land recovery)

65,000,000 * 0.1 /100 = $65,000

Commission is : $65,000

Sample commission calculation for NASHA ORB3 (sea recovery)

Because its a sea recovery we deduct 165,000 before the calculation

(72,650,000-165,000) *0.12/100 = $86,982

Commission is : $86,982

Sample commission calculation for CODC ORB3 (sea recovery)

Commission is : $0

Launch Schedule: It produces a launch schedule for the Rocket Engineers that launch the rockets. This schedule is for a given year and shows the date and type of launch for all customers with a launch in that year.

This schedule is for a given year entered by the user and shows the date and type of launch for all customers with a launch in that year.

Example Launch schedule (for 2020)
