10.23 LAB: Instrument information (derived classes)

 

Given the base class Instrument, define a derived class StringInstrument for string instruments.

USE PYTHON FOR THIS!

Ex: If the input is: Drums Zildjian 2015 2500 Guitar Gibson 2002 1200 6. 19 the output is: Instrument Information: Name: Drums Manufacturer: Zildjian Year built: 2015 Cost: 2500 Instrument Information: Name: Guitar Manufacturer: Gibson Year built: 2002 Cost: 1200 Number of strings: 6 Number of frets: 19 3446142153518.qxazay?
