Demo

Examples

on-demand mode

from pytchat import LiveChat

chat = LiveChat("DSGyEsJ17cI")
while chat.is_alive():
  data = chat.get()
  for c in data.items:
    print(f"{c.datetime} [{c.author.name}]-{c.message} {c.amountString}")
    data.tick()

callback mode

from pytchat import LiveChat
import time

#callback function is automatically called.
def display(data):
  for c in data.items:
    print(f"{c.datetime} [{c.author.name}]-{c.message} {c.amountString}")
    data.tick()

if __name__ == '__main__':
  chat = LiveChat("DSGyEsJ17cI", callback = display)
  while chat.is_alive():
    #other background operation.
    time.sleep(3)

asyncio context:

from pytchat import LiveChatAsync
from concurrent.futures import CancelledError
import asyncio

async def main():
  chat = LiveChatAsync("DSGyEsJ17cI", callback = func)
  while chat.is_alive():
    #other background operation.
    await asyncio.sleep(3)

#callback function is automatically called.
async def func(data):
  for c in data.items:
    print(f"{c.datetime} [{c.author.name}]-{c.message} {c.amountString}")
    await data.tick_async()

if __name__ == '__main__':
  try:
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
  except CancelledError:
    pass

youtube api compatible processor:

from pytchat import LiveChat, CompatibleProcessor
import time

chat = LiveChat("DSGyEsJ17cI", 
  processor = CompatibleProcessor() )

while chat.is_alive():
  data = chat.get()
  polling = data['pollingIntervalMillis']/1000
  for c in data['items']:
    if c.get('snippet'):
      print(f"[{c['authorDetails']['displayName']}]"
            f"-{c['snippet']['displayMessage']}")
      time.sleep(polling/len(data['items']))

replay:

If specified video is not live, automatically try to fetch archived chat data.

from pytchat import LiveChat

def main():
  #seektime (seconds): start position of chat.
  chat = LiveChat("ojes5ULOqhc", seektime = 60*30)
  print('Replay from 30:00')
  while chat.is_alive():
    data = chat.get()
    for c in data.items:
      print(f"{c.elapsedTime} [{c.author.name}]-{c.message} {c.amountString}")
      data.tick()

if __name__ == '__main__':
  main()
