Example 3: class in python
class ComplexNumber:
def __init__(self, r=0, i=0):
self.real = r
self.imag = i
def get_data(self):
print(f'{self.real}+{self.imag}j')
num1 = ComplexNumber(2, 3)
num1.get_data()
num2 = ComplexNumber(5)
num2.attr = 10
print((num2.real, num2.imag, num2.attr))
print(num1.attr)
Example 4: how to use class's in python
class person:
name = "jake"
