Flask - WebSocket and Real-Time

Asend(message, room='lobby', include_self=False)

Bsend(message, room='lobby', include_self=True)

Csend(message, broadcast=True)

Dsend(message, room='lobby')

Step-by-Step Solution

Solution:

Step 1: Understand sending to a room excluding sender
To send a message to a room but exclude the sender, use include_self=False.
Step 2: Match parameters to desired behavior
send(message, room='lobby', include_self=False) uses send with room='lobby' and include_self=False, which sends to all in 'lobby' except sender.
Final Answer:
send(message, room='lobby', include_self=False) -> Option A
Quick Check:
include_self=False excludes sender [OK]

Quick Trick: Use include_self=False to exclude sender in room message [OK]

Common Mistakes:

MISTAKES

Using include_self=True sends to sender too
