如何用python编写这个方程式？

import math

def solve_quadratic_equation(a, b, c):
    # 计算判别式
    discriminant = b**2 - 4*a*c
    
    # 判断方程的根的情况
    if discriminant > 0:
        # 两个不同的实根
        root1 = (-b + math.sqrt(discriminant)) / (2*a)
        root2 = (-b - math.sqrt(discriminant)) / (2*a)
        return root1, root2
    elif discriminant == 0:
        # 两个相同的实根
        root = -b / (2*a)
        return root, root
    else:
        # 两个复数根
        real_part = -b / (2*a)
        imaginary_part = math.sqrt(-discriminant) / (2*a)
        return complex(real_part, imaginary_part), complex(real_part, -imaginary_part)

# 示例：求解方程 x^2 - 2x + 1 = 0
a = 1
b = -2
c = 1
roots = solve_quadratic_equation(a, b, c)
print(f"方程的根为：{roots}")
