密码生成器(如何将构造函数添加到此程序)

import random
import string

class PasswordGenerator:
    def __init__(self, length=8, include_digits=True, include_letters=True, include_symbols=False):
        self.length = length
        self.include_digits = include_digits
        self.include_letters = include_letters
        self.include_symbols = include_symbols

    def generate_password(self):
        characters = ''
        if self.include_digits:
            characters += string.digits
        if self.include_letters:
            characters += string.ascii_letters
        if self.include_symbols:
            characters += string.punctuation

        if not characters:
            raise ValueError("At least one character type should be included.")

        password = ''.join(random.choice(characters) for _ in range(self.length))
        return password

# 创建一个密码生成器对象
generator = PasswordGenerator(length=10, include_digits=True, include_letters=True, include_symbols=True)

# 生成密码
password = generator.generate_password()
print(password)
