Hello,
in Python (contrary to Perl, for instance) there is one way to do common
tasks. Could somebody explain me what is the official python way of
printing unicode strings?
I tried to do this such way:
s = u"Stanisław Lem"
print u.encode('utf-8')
This works, but is very cumbersome.
Then I tried

Oh, maybe it's not cumbersome, but a little bit strange - but sure, I c
Hello,
I have such program:
import time
import thread
def f():
global lock
while True:
lock.acquire()
print thread.get_ident()
time.sleep(1)
lock.release()
lock=thread.allocate_lock()
thread.start_new_thread(f,())
thread.start_new_thread(f,())
time.sleep(60)
Thanks for answers.
But what about my main question? Is it possible to release GIL without
sleeping? I know that in this example situation I can achieve my goals
without that - I can just move sleep outside of locked block. But I
just want to know it for future - can I just do something like
thread
Hello,
there is something I don't understand about list comprehensions.
I understand how does this work:
print [[y for x in range(8)] for y in range(8)]
However I don't understand why this one works:
print [[y for y in range(8)] for y in range(8)]
In this second example I have one loop nested i

Hello,
I would like to use a callable object as a method of a class. So, when I
have such normal class:
class f:
version = 17
def a(self):
return self.version
f1 = f()
print f1.a()
I want to change it to something like that:
class add:
def __call__(self
