Let’s Play with Numbers!!!

Write the ComplexNumber class so that the following code generates the output below.

class RealNumber:
def __init__(self, r=0): self.__realValue = r def getRealValue(self):
return self.__realValue def setRealValue(self, r): self.__realValue = r def __str__(self):
return 'RealPart: '+str(self.getRealValue())
cn1 = ComplexNumber() print(cn1) print('---------') cn2 = ComplexNumber(5,7) print(cn2) OUTPUT:
RealPart: 1.0
ImaginaryPart: 1.0
--------------------
RealPart: 5.0
ImaginaryPart: 7.0














Write the ComplexNumber class so that the following code generates the output below.

class RealNumber: def __init__(self, number=0):
self.number = number def __add__(self, anotherRealNumber):
return self.number + anotherRealNumber.number def __sub__(self, anotherRealNumber): return self.number - anotherRealNumber.number def __str__(self):
return str(self.number)
r1 = RealNumber(3) r2 = RealNumber(5) print(r1+r2)
cn1 = ComplexNumber(2, 1)
print(cn1)
cn2 = ComplexNumber(r1, 5) print(cn2) cn3 = cn1 + cn2 print(cn3) cn4 = cn1 - cn2
print(cn4)
OUTPUT:
8
2 + 1i
3 + 5i
