Using Slack API from Python

I am following the following tutorial Slack API tutorial to post a message on slack. I already created Slack application and was able to use it with Incoming Webhooks now I would like to use API from python. So I tried:

import os
from slackclient import SlackClient
slack_token = 'xoxp-long-sequence-of-numbers'
sc = SlackClient(slack_token)

sc.api_call(
  "chat.postMessage",
  channel="my_test_channel",
  text="Hello from Python! :tada:"
)

I got back the following error message:

    {'error': 'missing_scope',
 'headers': {'Access-Control-Allow-Headers': 'slack-route, x-slack-version-ts',
  'Access-Control-Allow-Origin': '*',
  'Access-Control-Expose-Headers': 'x-slack-req-id',

  'X-Via': 'haproxy-www-km3w',
  'X-XSS-Protection': '0'},
 'needed': 'chat:write:user',
 'ok': False,
 'provided': 'identify,incoming-webhook'}

My channel name is literally: my_test_channel. Probably I need to use different name, but how can I find it out?

UPDATE

So I found out encoded channel id and changed my script to:

import os
    from slackclient import SlackClient
    slack_token = 'xoxp-long-sequence-of-numbers'
    sc = SlackClient(slack_token)

    sc.api_call(
      "chat.postMessage",
      channel="CHXXXXXXX",
      text="Hello from Python! :tada:"
    )

but error back is still missing scope

It looks like its missing the user option according to the error ('needed': 'chat:write:user'):

    sc.api_call(
      "chat.postMessage",
      channel="my_test_channel",
      text="Hello from Python! :tada:"
      user="U0XXXXXXX"
    )
