I am designing a turn-based game that uses connection.recv() to read from the socket and store the data of a 'move' in a buffer (which the server reads from). The problem is, the player can send data outside of their turn to be queued in the socket buffer, which means the server potentially reads from moves they made outside of their turn, instead of blocking until they make a turn. Is there any way to flush the data stored in the socket, and if not, is there any other workaround to this problem?

From Steffen's suggestion, I am using recv calls to clear the buffer. Currently, I'm setting the socket to non-blocking and calling recv until a BlockingIOError. It would be much appreciated if anyone could point out a more graceful solution (that doesn't use exceptions).
connection.setblocking(False)
while True:
try:
chunk = connection.recv(4096)
except BlockingIOError as b:
break
connection.setblocking(True)
.flush()on the client side after writing to the makefile.
