class Client(Methods, BaseClient): """This class represents a Client, the main mean for interacting with Telegram. 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. proxy (``dict``, *optional*): Your SOCKS5 Proxy settings as dict, e.g.: *dict(hostname="11.22.33.44", port=1080, username="******", password="******")*. *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``, *optional*): Pass your phone number (with your Country Code prefix included) to avoid entering it manually. Only applicable for new sessions. phone_code (``str`` | ``callable``, *optional*): Pass the phone code as string (for test numbers only), or pass a callback function which accepts a single positional argument *(phone_number)* and must return the correct phone code (e.g., "12345"). Only applicable for new sessions. password (``str``, *optional*): Pass your Two-Step Verification password (if you have one) to avoid entering it manually. 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*): Thread pool size 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.
