请你用 python 做一个复杂的原神抽卡模拟器

好的，我可以为您编写一个基于 Python 的原神抽卡模拟器。下面是一个大致的实现流程：

1. 定义角色和武器类，包括属性（如名字、星级、属性加成等）和方法（如抽卡、计算概率等）。
2. 设计抽卡概率，包括普通池和角色池的概率，以及 pity 机制等。
3. 实现抽卡逻辑，包括根据概率随机抽取角色或武器、计算 pity 次数等。
4. 编写 UI 界面，包括展示已有角色和武器、展示抽卡结果、统计概率等。

以下是一个简单的代码示例：

import random

class Character:
    def __init__(self, name, star_level, attribute):
        self.name = name
        self.star_level = star_level
        self.attribute = attribute
        self.is_obtained = False

    def obtain(self):
        self.is_obtained = True

class Weapon:
    def __init__(self, name, star_level, attribute):
        self.name = name
        self.star_level = star_level
        self.attribute = attribute
        self.is_obtained = False

    def obtain(self):
        self.is_obtained = True

class Gacha:
    def __init__(self):
        self.characters = [
            Character('Amber', 4, 'Pyro'),
            Character('Diluc', 5, 'Pyro'),
            Character('Jean', 5, 'Anemo'),
            # ...
        ]
        self.weapons = [
            Weapon('Skyward Harp', 5, 'Bow'),
            Weapon('Lion\'s Roar', 4, 'Sword'),
            Weapon('The Bell', 4, 'Claymore'),
            # ...
        ]
        self.pity_counter = 0
        self.pity_limit = 90

    def roll(self):
        is_character_pool = random.random() < 0.5  # assume 50/50 chance
        if is_character_pool:
            items = self.characters
            probability = [0.006, 0.051, 0.282, 0.5, 0.16]  # 5-star to 4-star probability
            pity_probability = [0.006, 0.051, 0.282, 0.5, 0.16]  # pity probability
        else:
            items = self.weapons
            probability = [0.007, 0.06, 0.324, 0.6, 0.009]  # 5-star to 4-star probability
            pity_probability = [0.007, 0.06, 0.324, 0.6, 0.009]  # pity probability

        # calculate the probability of obtaining each item
        total_probability = sum(probability)
        probability = [p / total_probability for p in probability]

        # roll the gacha
        item = None
        if self.pity_counter >= self.pity_limit:
            # pity, force to obtain a 5-star item
            item = random.choices(items, weights=pity_probability)[0]
            self.pity_counter = 0
        else:
            # normal roll
            item = random.choices(items, weights=probability)[0]
            self.pity_counter += 1

        item.obtain()

        return item

gacha = Gacha()
for i in range(10):
    item = gacha.roll()
    print(f'Obtained {item.star_level}-star {type(item).__name__}: {item.name}')

这是一个简单的抽卡模拟器，仅供参考。您可以根据自己的需求进行扩展和优化。同时，为了更好的用户体验，您可以使用 Pygame 等库来实现 UI 界面。
