python - Telethon / Telegram - Convert tData to sessionString for Telethon

Hello, given: - tdata-Folder - [login to view URL] - (api_id, api_hash) When you put them in Telegram Desktop (Official) - Portable Version in the Folder, then if you start Telegram you are directly logged in and authenticated, directly usable. (This works on Windows, but should work also on linux ( i think ~/.local/shar/TelegramDesktop/tdata) I want to use telethon, but for that i have to authenticate first on TG (insert the code which TG sends me to the TG Application). After that i can print a session string, with that string i dont have to authenticate it a second time. I want to automate this step. I see 2 possible Solutions (but feel free to get your own way): - convert tdata directly to Telethon session - write a script which extracts the code from the text_Message in Telegram Desktop Application After that i can construct the sessionString myself - export the chats and find the typical code Key requirements: - no User interaction requiered (not once) - i put tdata-directory, [login to view URL] and your script / helpers in a folder, and when i execute the script it should output the registration-code / auth-code (or the message from telegram) Example tData-directory and [login to view URL] can be provided if asked
