Telegram API: how to get username from id (Python telepot)?

Question

I save ids of all users of my bot in a database but how can I get their current username if I know id? I'm using Python 3 and Telepot framework.

Answer 1

Information about a user from user_id can be obtained by the getChat method in telepot.

bot = telepot.Bot(TOKEN)
info = bot.getChat(user_id)
print(info)

Answer 2

you can get the inforamtion of an account by checking the entity.

You can try to get the entity with this method:

entity = client.get_entity(chat_id)

then Print the entity and try to get the name from there with something like name = entity.chat.name
