请给出使用request库爬取有道翻译实现模仿有道翻译的功能的代码

以下是使用request库爬取有道翻译并实现模仿有道翻译功能的Python代码：

import requests
import hashlib
import time
import random
import json


def generate_sign(word):
    # 生成 sign 参数
    salt = str(int(time.time() * 1000) + random.randint(1, 10))
    sign_str = "fanyideskweb" + word + salt + "p09@Bn{h02_BIEe]$P^nG"
    sign = hashlib.md5(sign_str.encode("utf-8")).hexdigest()
    return sign, salt


def translate(word):
    url = "http://fanyi.youdao.com/translate_o?smartresult=dict&smartresult=rule"

    headers = {
        "Accept": "application/json, text/javascript, */*; q=0.01",
        "Accept-Encoding": "gzip, deflate",
        "Accept-Language": "en-US,en;q=0.9,zh-CN;q=0.8,zh;q=0.7",
        "Connection": "keep-alive",
        "Content-Length": "238",
        "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",

        "Host": "fanyi.youdao.com",
        "Origin": "http://fanyi.youdao.com",
        "Referer": "http://fanyi.youdao.com/",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.93 Safari/537.36",
        "X-Requested-With": "XMLHttpRequest"
    }

    data = {
        "i": word,
        "from": "AUTO",
        "to": "AUTO",
        "smartresult": "dict",
        "client": "fanyideskweb",
        "salt": "",
        "sign": "",
        "lts": "",
        "bv": "7e4d4f9b9c116b6a546f3c3bb2d8fcb7",
        "doctype": "json",
        "version": "2.1",
        "keyfrom": "fanyi.web",
        "action": "FY_BY_REALTlME"
    }

    sign, salt = generate_sign(word)
    data["salt"] = salt
    data["sign"] = sign
    data["lts"] = str(int(time.time() * 1000))

    response = requests.post(url, headers=headers, data=data)
    result = json.loads(response.text)

    return result["translateResult"][0][0]["tgt"]


if __name__ == "__main__":
    while True:
        word = input("请输入要翻译的单词或句子（输入 q 退出）：")
        if word == "q":
            break
        result = translate(word)
        print(result)

运行代码后，会提示输入要翻译的单词或句子。输入后，程序会输出翻译结果。如果输入 q，则程序退出。
