Hi, I am Shao Ren, I see you have a need for an English to Chinese translator for a Python 3 manual. I definitely feel that I can offer you the best bang for your buck, and here's why:
1) I'm Malaysian, that may not mean much, but I've been learning, speaking and communicating in both Chinese and English since I was born. I'm fluent in both the languages, and can definitely deliver. I have done prior translation work for cosmetic and vacation companies, and as such can guarantee that I have the skills to deliver.
2) Having spoken both English and Chinese for such a long time, I can avoid the pitfalls of using 'book speak', where uncommon words are preferred over the usual words regular people use to communicate. This will definitely help if your book is aimed at native Chinese Speakers.
3) I am a Python user myself. My degree was obtained in Computational Physics, and my main programming language throughout my thesis research was Python 3, mainly dealing with complex network analysis. I also happen to have interned at a company dealing with ASP.NET, which dealt with HTML a ton. This means that I can better present your ideas due to a native understanding of the source material.
I hope that we can get the chance to work together. If anything I said feels that it could help, feel free to let me know! Here's wishing you a great day.
