Description
pytchat is a python library for fetching youtube live chat without using youtube api, Selenium or BeautifulSoup.

Install
pip install pytchat
Demo
Examples
on-demand mode
from pytchat import LiveChat
chat = LiveChat("rsHWP7IjMiw")
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("rsHWP7IjMiw", 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("rsHWP7IjMiw", 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("rsHWP7IjMiw",
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 = ReplayChat("ojes5ULOqhc", seektime = 60*30)
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()
