When starting client the code is asking for phone/bot token

Question

While running my first code using Telethon library, it is asking for a bot token.

This is the actual code:

from telethon import TelegramClient, events, sync
api_id = 1234567
api_hash = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
client = TelegramClient('anon', api_id, api_hash)
client.start()

And on command prompt:

pip3 install telethon

python3 C:/TG/First.py

Result:

Please enter your phone (or bot token)

If I give my API ID, it eventually throws the error:

telethon.errors.rpcerrorlist.PhoneNumberInvalidError: The phone number is invalid (caused by SendCodeRequest)

Why? I expect the client to start without errors.

PS: my API ID is 7 digits long.

This will only occure at your first use just enter your Phone Number starting with + then you will recive a code which you have to enter next. This is just to Authorise your Laptop beeing loged in to Telegram.
