Python复数类实现：加减运算

class Complex:
    def __init__(self, real, imaginary):
        self.real = real
        self.imaginary = imaginary

    def add(self, other):
        real_sum = self.real + other.real
        imaginary_sum = self.imaginary + other.imaginary
        return Complex(real_sum, imaginary_sum)

    def subtract(self, other):
        real_diff = self.real - other.real
        imaginary_diff = self.imaginary - other.imaginary
        return Complex(real_diff, imaginary_diff)

使用示例：

# 创建两个复数对象
c1 = Complex(2, 3)
c2 = Complex(4, 5)

# 计算两个复数的和
sum_result = c1.add(c2)
print(f'Sum: {sum_result.real} + {sum_result.imaginary}i')

# 计算两个复数的差
diff_result = c1.subtract(c2)
print(f'Difference: {diff_result.real} + {diff_result.imaginary}i')

输出结果为：

Sum: 6 + 8i
Difference: -2 - 2i
