设计一个复数类实现复数加减乘除

好的，这是一个计算类的问题，我可以回答。以下是一个复数类的示例代码：

class Complex:
    def __init__(self, real, imag):
        self.real = real
        self.imag = imag
        
    def __add__(self, other):
        real = self.real + other.real
        imag = self.imag + other.imag
        return Complex(real, imag)
    
    def __sub__(self, other):
        real = self.real - other.real
        imag = self.imag - other.imag
        return Complex(real, imag)
    
    def __mul__(self, other):
        real = self.real * other.real - self.imag * other.imag
        imag = self.real * other.imag + self.imag * other.real
        return Complex(real, imag)
    
    def __truediv__(self, other):
        denom = other.real**2 + other.imag**2
        real = (self.real * other.real + self.imag * other.imag) / denom
        imag = (self.imag * other.real - self.real * other.imag) / denom
        return Complex(real, imag)
    
    def __str__(self):
        return f"{self.real} + {self.imag}i"

这个类可以用来表示复数，支持加减乘除四种运算。你可以像这样使用它：

a = Complex(2, 3)
b = Complex(4, 5)

c = a + b
print(c)  # 输出：6 + 8i

d = a - b
print(d)  # 输出：-2 - 2i

e = a * b
print(e)  # 输出：-7 + 22i

f = a / b
print(f)  # 输出：0.5609756097560976 + 0.0487804878048781i

希望这个例子能够帮到你。如果你还有其他问题，请继续提出。
