翻译脚本无法生效,求Python前辈指点迷津。

该脚本的作用是把英文文档变成中英文混合模式,以便翻译使用。但运行结果却没有一句能翻译成功,全都是KeyError,最后就是UnicodeEncodeError。

# -*- coding: utf-8 -*-

# Python版本:3.6,搜狗翻译API,ID和Key均可用。
# 该脚本作用:把从FF下载的文本文档按句回车,再把上面句的机翻结果自动插入下面。

例:
处理前:A Word of Caution (1).txt
You are Twilight, and today in a difficult situation. Applejack has adopted some creature from the Everfree forest. And while it seems harmless enough to AJ and everyone else, even the Princess, you're not so sure. Never before has anybody seen anything like him.

处理后:out_A Word of Caution (1).txt
You are Twilight, and today in a difficult situation.
>>你是暮光之城,今天处境艰难。
Applejack has adopted some creature from the Everfree forest.
>>Applejack采用了Everfree森林中的一些生物。
And while it seems harmless enough to AJ and everyone else, even the Princess, you're not so sure.
>>尽管对于AJ和其他所有人,甚至是公主来说,它似乎都是无害的,但你并不那么确定。
Never before has anybody seen anything like him.
>>从来没有人见过像他这样的人。

        思路修正
        在预处理之中,应该可以直接调用翻译函数/方法,
        从文本中读取的每一行都要进行翻译处理,
        再以“>>机翻文本\n”的方式加到当前行后面。

如果问题得到解决,请点我回答左上角的采纳和向上的箭头,谢谢。

response = requests.request("POST", url, data=payload, headers=headers)
->
response = requests.request("POST", url, data=payload.encode(), headers=headers)
