Python script that invokes Google translation, depending on `requests` library.

gtranslate.py

import json
import sys

import requests

tl, query = sys.argv[1:]
sl = 'auto'
ua = ('Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) '
      'Gecko/20100101 Firefox/109.0')
query = query.strip()

# json response from Google transaltion server
jr = requests.get(
    'https://translate.googleapis.com/translate_a/single',
    params={
        'client': 'gtx',
        'sl': sl,
        'tl': tl,
        'dt': 't',
        'q': query,
    },
    headers={
        'user-agent': ua,
    }).json()
# the translation result
tr = ''.join(x[0] for x in jr[0])
print(tr)
