why does the following with Queue, q.put('\x02', True) not put itin the queue?

[Gabriel Rossetti]

Hello,

I'm having some trouble with the Queue class, for some reason, if I do
this (ch == ) :

q = Queue.Queue(0)
repr(ch)
q.put(ch, True)
len(q.queue)

where the output is :

'\x02'
0

why isn't the character/string being put it in the queue?

Thank you,
Gabriel

yes, if you do it that way (s = '\x02') it works, but I read the data
from a file, and I that way it doesn't work....

It does work (using Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45)
[MSC v.1310 32 bit (Intel)] on win32)

import Queue
f = open('temp', 'w')
f.write('\x02')
f.close()

f = open('temp', 'r')
ch = f.read(1)
f.close()

print repr(ch)
q = Queue.Queue(0)
q.put(ch, True)
print len(q.queue)

prints the following:
'\x02'

Perhaps you could put together an example that actually shows the
behavior you're seeing. I'm not super familiar with Queue.Queue
internals, but should you be accessing the undocumented q.queue (the
internal deque of the Queue instance) directly? Shouldn't you be
using the documented q.qsize() interface instead?
