Given the base class Instrument, define a derived class StringInstrument for string instruments. Ex: If the input is: Drums Zildjian 2015 2500 Guitar Gibson 2002
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Given the base class Instrument, define a derived class StringInstrument for string instruments.
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
code to be used:
class Instrument:
def __init__(self, name, manufacturer, year_built, cost):
self.name = name
self.manufacturer = manufacturer
self.year_built = year_built
self.cost = cost
def print_info(self):
print('Instrument Information:')
print(' Name:', self.name)
print(' Manufacturer:', self.manufacturer)
print(' Year built:', self.year_built)
print(' Cost:', self.cost)
class StringInstrument(Instrument):
# TODO: Define constructor with attributes:
# name, manufacturer, year_built, cost, num_strings, num_frets
if __name__ == "__main__":
instrument_name = input()
manufacturer_name = input()
year_built = int(input())
cost = int(input())
string_instrument_name = input()
string_manufacturer = input()
string_year_built = int(input())
string_cost = int(input())
num_strings = int(input())
num_frets = int(input())
my_instrument = Instrument(instrument_name, manufacturer_name, year_built, cost)
my_string_instrument = StringInstrument(string_instrument_name, string_manufacturer, string_year_built, string_cost, num_strings, num_frets)
my_instrument.print_info()
my_string_instrument.print_info()
print(' Number of strings:', my_string_instrument.num_strings)
print(' Number of frets:', my_string_instrument.num_frets)
