Python uses google translation to translate subtitle files

Python uses Google Translate API to translate subtitle files

English subtitles are really a headache, so I spent a day studying it and implemented a relatively simple translation code with python. Only a few dozen lines

Load the module first

pip uninstall googletrans
git clone https://github.com/BoseCorp/py-googletrans.git
cd ./py-googletrans && python setup.py install

Use test

from googletrans import Translator

# 实例化
translator = Translator(service_urls=['translate.google.cn'])

content = 'Today is a gooday'

print(translator.translate(content, dest='zh-CN').text.encode('utf-8').decode('utf-8'))

The output is fine

Idea:
Read the content of the file by line and translate the subtitles of a specific line. It is very simple, but you must pay attention to the encoding problem

from googletrans import Translator
# encoding=utf-8
import argparse


def main(args):
    # 实例化
    translator = Translator(service_urls=['translate.google.cn'])
    f = open(args.fs, 'r+', encoding="utf-8")
    flist = f.readlines()
    f = open(args.fs, 'w+', encoding="utf-8")
    f.writelines(flist)
    for x in range(4, len(flist)):
        if x % 4 == 0:
            print(x)
            flist[x] = translator.translate(flist[x], dest='zh-CN').text.encode('utf-8').decode('utf-8') + "\n"
            print(translator.translate(flist[x], dest='zh-CN').text.encode('utf-8').decode('utf-8'))
            f = open(args.fs, 'w+', encoding="utf-8")
            f.writelines(flist)


if __name__ == '__main__':
    parser = argparse.ArgumentParser(usage="it's usage tip.", description="help info.")
    parser.add_argument("--fs", type=str, required=True, help="the fileloacation")
    args = parser.parse_args()
    main(args)

Use demonstration:

python   tran.py  --fs  "D:\xiaxiaxia\pycharmtext\a.vtt"

Matters needing attention
Read lines, process them by line, and then pay attention to the encoding when writing and opening. When writing, you must add a newline character \n at the end so that there will be no errors.

The code is still relatively simple, and interested parties can be optimized in io processing and concurrency.
