If you are not Google, you do have this token and will have to pay for use. This class is the result of reverse engineering on the obfuscated and minified code used by Google to generate such token. The token is based on a seed which is updated once per hour and on the text that will be translated. Both are combined - by some strange math - in order to generate a final token (e.g. 744915.856682) which is used by the API to validate the request. This operation will cause an additional request to get an initial token from translate.google.com. Example usage: >>> from googletrans.gtoken import TokenAcquirer >>> acquirer = TokenAcquirer() >>> text = 'test' >>> tk = acquirer.do(text) >>> tk 950629.577246 z tkk:\'(.+?)\'rcCs&d|_d|vr ||_dSd||_dS)N0httpzhttps://)tkkhost)selfrrS/var/www/html/env_mimamsha/lib/python3.10/site-packages/translatepy/utils/gtoken.py__init__Us zTokenAcquirer.__init__cCs4tttdd}|jrt|jdd|krdSt|jtd}|j |j }|r4| d|_dSz|j |j  d dd }| d }WntyVtd ty]w|rt|}d }d }dtddd}} t|D]}} t| tjr| jdj} | | vrt| jtjr| jj| | <qxt| jtjrt| jjtjr| jjj | | <qxt| tj rd}qx|rt| tjr| j}qx|r|dkrt| tj!rqxt| tj"rd}qxt| tj#rd}qxt| tj$rd}qxt| tj%rd}qxt&d'|| d| dd d} t(| tid} d'|| }||_dSdS)zupdate tkk ig@wKA.rN)headerszvar zunicode-escapezrCould not find TKK token for this request.
