Using Python 3 is very simple:

from time import sleep

from telethon import TelegramClient

from telethon.tl.functions.channels import GetParticipantsRequest
from telethon.tl.types import ChannelParticipantsSearch

api_id = <app_id>
api_hash = '<app_hash>'
phone = '[phone]'
group_link = 't.me/joinchat/<group_hash>'

client = TelegramClient('session_name', api_id, api_hash)
client.connect()
channel = client.get_entity(group_link)

if not client.is_user_authorized():
    client.send_code_request(phone)
    client.sign_in(phone, input('Please Enter the verification code: '))

def get_users(a_channel):
    offset = 0
    limit = 100
    all_participants = []
    while True:
        participants = client.invoke(GetParticipantsRequest(
            a_channel, ChannelParticipantsSearch(''), offset, limit, hash=0
        ))
        if not participants.users:
            break
        all_participants.extend(participants.users)
        offset += len(participants.users)
        sleep(1)
    return all_participants

def print_users(a_users):
    for user in a_users:
        print(user.username)

print_users(get_users(channel))
