socket: Did I find a bug?

This is on a debian 9 box python 2.7.13 My interpretation is that a timeout exception is thrown and that the args attribute of such an exception is an empty tuple which then causes an IndexError in line 482 of module /usr/lib/python2.7/socket.py. Does that soundplausible? Here is the traceback:

psychocomputational analysis toolkit in Python?

You might find MNE useful, and if what you're doing happens to fit somewhere in their package you could contribute to it -- they're a good group to work with. https://www.martinos.org/mne/stable/index.html https://github.com/mne-tools/mne-python -- https://mail.python.org/mailman/listinfo/python-

Re: psychocomputational analysis toolkit in Python?

OK I got it, thank you! :) Essentially, I want to develop a psychocomputational analysis toolkit in Python for studying real-time neuroimaging data (of cortical activity) from low-intensity, focused ultrasounds (LIFU) and possibly emulate a functional brain-to-brain coupling system on my 32-bi

Unnoticed traceback in a thread

Thank you guys, lots of great answers, very helpful. I got it! A follow-up question: How did the value of "object" get passed to "time"? Obviously, they have different names. How did Python make that connection? Code is below for convenience. class Clock(object): def __init__(self, time):

I am a student studying Python in Korea. I found strange thing while studying through idle

If you type print (" hello\ rpython ") into the python 3.7.0.b2, only the python is printed and i learned it's a crystal. However, if you type print (" hello\ rpython ") in the python 3.7.0.b2 idle, it is output as hellopython. I wonder why it prints like this. I would appreciate your answer.
