hello all
Hello all, I am just starting out on learning Python and joined this list. I have grabbed the Learning Perl book by Mark & David. This book really seems good so far.. the concepts are explained pretty nicely. :) I have a background a bit in Java but Python seems so cooler. The concept of Dynamically assigning values n the objects springing into existence is really nice to see especially you don't have to declare variable everytime its used. In this book though it says Python 3.0 as upcoming python version but all i see so far is Python 2.4 ?? Any hints anyone has? So contrasting with Java which is a bit like C++ where values and object has to be "created" before assigning, Python seems very typical of "on the edge" language, "ready to go" language :) cheers, Ishwor -- http://mail.python.org/mailman/listinfo/python-list

Scipy needs various libraries.

You join the processes when you want it to return with or without optional parameter `timeout' in this case. Let me be more specific. The doc for Process says: "join([timeout]) Block the calling thread until the process whose join() method is called terminates or until the optional timeout occurs." Right. Now, the join( ) here is going to be the the called process' join( ). If this particular join( ) waits indefinitely, then your parent process' join( ) will _also_ wait indefinitely waiting for the child processes' join( ) to finish up __unless__ you define a timeout value. > Any ideas why this is happening? Have a look below. If I've understood your code, then it will be reflective of your situation but with different take on the implementation side of things (ran on Python2.6): from multiprocessing import Process, Queue; from Queue import Empty; import sys; def _process_worker(q): try: something = q.get(block=False, timeout=None); except Empty: print sys.exc_info(); else: print 'Removed %d from the queue' %something; def _make_some_processes(): q = Queue(); for i in range(3): for j in range(3): q.put(i*30+j); while not q.empty(): p = Process(target=_process_worker, args=(q,)); p.start(); p.join(); if __name__ == "__main__": _make_some_processes(); ''' Removed 0 from the queue Removed 1 from the queue Removed 2 from the queue Removed 30 from the queue Removed 31 from the queue Removed 32 from the queue Removed 60 from the queue Removed 61 from the queue Removed 62 from the queue ''' -- Regards, Ishwor Gurung -- http://mail.python.org/mailman/listinfo/python-list

Re: importing with .m instead of .py
Wanderer Hi Refer to http://docs.python.org/tutorial/modules.html#the-module-search-path. Particularly- " When a module named spam is imported, the interpreter searches for a file named spam.py in the current directory, and then in the list of directories specified by the environment variable PYTHONPATH. This has the same syntax as the shell variable PATH, that is, a list of directory names. When PYTHONPATH is not set, or when the file is not found there, the search continues in an installation-dependent default path; on Unix, this is usually .:/usr/local/lib/python.
