This is a method belonging to a class. We don't know what the class is,
because you haven't shown it, so let's just call it "MyClass".
The method takes two arguments (msgs and time) plus a special
argument, "self", which represents the instance where the method is called.
So at some point, you must say:
instance = MyClass()
Do you understand object oriented programming? Have you programmed in any
other languages?
My *guess* is that the "msgs" argument is probably a list of messages:
the_messages = [first_message, second_message, third_message]
and the "time" argument is possibly a number (time in seconds?):
some_time = 125
Then you call the method:
instance.receive_messages(the_messages, some_time)
When you call the receive_messages method, the following happens:
- each of the messages are taken in turn, one at a time, and a method on
that message is called:
for msg in msgs:
msg.set_recv_time(time)
Translation:
for each message first_message, second_message, ...
call method "set_recv_time" with argument some_time
- then the original instance calls one of its own messages, probably to
store those messages:
self.msgs_received.extend(msgs)
I can't be more detailed, as I don't know how much programming experience
you have, or what the class that this method came from does.
