Random access isn't supported by the defined interface. You can make
it more convenient, though.
import Queue
class IterQueue( Queue.Queue ):
def __iter__( self ):
return self
def next( self ):
if self.empty():
raise StopIteration
return self.get()
q= IterQueue()
q.put( 'a' )
q.put( 'b' )
q.put( 'c' )
print [ x for x in q ]
/Output:
['a', 'b', 'c']
