If session has a key in it with the value "name" it returns the value associated with that key (which might well be False), otherwise (if there is no key named "name") it returns False.
The session is a dictionary-like type so the best place to get documenation on the get method is in the Python docs for the standard library. The short of the matter is that get is shorthand for the following:
if "name" in request.session:
result = request.session["name"]
else:
result = False
if result:
# Do something

As per Django docs the 2nd argument of the get method is the default. So "request.session.get("name",False):" statement returns the value of the 'name' items if it exists in the session if it doesn't then a default of False is returned.
