It exposes bot-like methods for an easy access to the API as well as a simple way to invoke every single Telegram API method available. Args: session_name (``str``): Name to uniquely identify a session of either a User or a Bot. For Users: pass a string of your choice, e.g.: "my_main_account". For Bots: pass your Bot API token, e.g.: "123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11" Note: as long as a valid User session file exists, Pyrogram won't ask you again to input your phone number. api_id (``int``, *optional*): The *api_id* part of your Telegram API Key, as integer. E.g.: 12345 This is an alternative way to pass it if you don't want to use the *config.ini* file. api_hash (``str``, *optional*): The *api_hash* part of your Telegram API Key, as string. E.g.: "0123456789abcdef0123456789abcdef" This is an alternative way to pass it if you don't want to use the *config.ini* file. app_version (``str``, *optional*): Application version. Defaults to "Pyrogram \U0001f525 vX.Y.Z" This is an alternative way to set it if you don't want to use the *config.ini* file. device_model (``str``, *optional*): Device model. Defaults to *platform.python_implementation() + " " + platform.python_version()* This is an alternative way to set it if you don't want to use the *config.ini* file. system_version (``str``, *optional*): Operating System version. Defaults to *platform.system() + " " + platform.release()* This is an alternative way to set it if you don't want to use the *config.ini* file. lang_code (``str``, *optional*): Code of the language used on the client, in ISO 639-1 standard. Defaults to "en". This is an alternative way to set it if you don't want to use the *config.ini* file. ipv6 (``bool``, *optional*): Pass True to connect to Telegram using IPv6. Defaults to False (IPv4). proxy (``dict``, *optional*): Your SOCKS5 Proxy settings as dict, e.g.: *dict(hostname="11.22.33.44", port=1080, username="user", password="pass")*. *username* and *password* can be omitted if your proxy doesn't require authorization. This is an alternative way to setup a proxy if you don't want to use the *config.ini* file. test_mode (``bool``, *optional*): Enable or disable log-in to testing servers. Defaults to False. Only applicable for new sessions and will be ignored in case previously created sessions are loaded. phone_number (``str`` | ``callable``, *optional*): Pass your phone number as string (with your Country Code prefix included) to avoid entering it manually. Or pass a callback function which accepts no arguments and must return the correct phone number as string (e.g., "391234567890"). Only applicable for new sessions. phone_code (``str`` | ``callable``, *optional*): Pass the phone code as string (for test numbers only) to avoid entering it manually. Or pass a callback function which accepts a single positional argument *(phone_number)* and must return the correct phone code as string (e.g., "12345"). Only applicable for new sessions. password (``str``, *optional*): Pass your Two-Step Verification password as string (if you have one) to avoid entering it manually. Or pass a callback function which accepts a single positional argument *(password_hint)* and must return the correct password as string (e.g., "password"). Only applicable for new sessions. recovery_code (``callable``, *optional*): Pass a callback function which accepts a single positional argument *(email_pattern)* and must return the correct password recovery code as string (e.g., "987654"). Only applicable for new sessions. force_sms (``str``, *optional*): Pass True to force Telegram sending the authorization code via SMS. Only applicable for new sessions. first_name (``str``, *optional*): Pass a First Name to avoid entering it manually. It will be used to automatically create a new Telegram account in case the phone number you passed is not registered yet. Only applicable for new sessions. last_name (``str``, *optional*): Same purpose as *first_name*; pass a Last Name to avoid entering it manually. It can be an empty string: "". Only applicable for new sessions. workers (``int``, *optional*): Number of maximum concurrent workers for handling incoming updates. Defaults to 4. workdir (``str``, *optional*): Define a custom working directory. The working directory is the location in your filesystem where Pyrogram will store your session files. Defaults to "." (current directory). config_file (``str``, *optional*): Path of the configuration file. Defaults to ./config.ini plugins_dir (``str``, *optional*): Define a custom directory for your plugins. The plugins directory is the location in your filesystem where Pyrogram will automatically load your update handlers. Defaults to None (plugins disabled). no_updates (``bool``, *optional*): Pass True to completely disable incoming updates for the current session. When updates are disabled your client can't receive any new message. Useful for batch programs that don't need to deal with updates. Defaults to False (updates enabled and always received). takeout (``bool``, *optional*): Pass True to let the client use a takeout session instead of a normal one, implies no_updates. Useful for exporting your Telegram data. Methods invoked inside a takeout session (such as get_history, download_media, ...) are less prone to throw FloodWait exceptions. Only available for users, bots will ignore this parameter. Defaults to False (normal session).
