|
|
|
Other features:
|
|
+ Customizable chat data processors including yt api compatible one.
|
|
+ Available on asyncio context.
|
|
+ Quick fetching of initial chat data by generating continuation params
|
|
instead of web scraping.
|
|
|
|
## Install
|
|
```
|
|
pip install pytchat
|
|
```
|
|
|
|
## Examples
|
|
```
|
|
from pytchat import LiveChat
|
|
|
|
chat = LiveChat("G1w62uEMZ74")
|
|
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
|
|
|
|
chat = LiveChat("G1w62uEMZ74", callback = func)
|
|
while chat.is_alive():
|
|
time.sleep(3)
|
|
|
|
def func(chatdata):
|
|
for c in chatdata.items:
|
|
print(f"{c.datetime} [{c.author.name}]-{c.message} {c.amountString}")
|
|
chat.tick()
|
|
```
|
|
|
|
asyncio context:
|
|
```
|
|
from pytchat import LiveChatAsync
|
|
import asyncio
|
|
|
|
async def main():
|
|
chat = LiveChatAsync("G1w62uEMZ74", callback = func)
|
|
while chat.is_alive():
|
|
#other background operation here.
|
|
await asyncio.sleep(3)
|
|
|
|
async def func(chat)
|
|
for c in chat.items:
|
|
print(f"{c.datetime} [{c.author.name}]-{c.message} {c.amountString}")
|
|
await chat.tick_async()
|
|
|
|
loop = asyncio.get_event_loop()
|
|
loop.run_until_complete(main())
|
|
```
|
|
|
|
|
|
yt api compatible processor:
|
|
```
|
|
from pytchat import LiveChat, CompatibleProcessor
|
|
|
|
chat = LiveChat("G1w62uEMZ74",
|
|
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"]))
|
|
|
|
```
|
|
|
