python-3.6

问题 Sorry for the long post but I've been poking at this for over a week so I've tried a lot of different stuff. I know Python well enough but I don't have any experience with asyncio or non-blocking functions in Python. I'm writing an API library/module/package/whatever for a web service that requires a websocket connection. There are many incoming messages to act on, and some control-related (web app level, not websocket control messages) that I need to send on occasion. I can easily receive

问题 Here is an executable code which works in Python 2.7 but results in an error in Python 3.6: import six class AMeta(type): def __new__(cls, name, bases, attrs): module = attrs.pop('__module__') new_attrs = {'__module__': module} classcell = attrs.pop('__classcell__', None) if classcell is not None: new_attrs['__classcell__'] = classcell new = super(AMeta, cls).__new__( cls, name, bases, new_attrs) new.duplicate = False legacy = super(AMeta, cls).__new__( cls, 'Legacy' + name, (new,), new_attrs

问题 I am trying to play a sound at the end of a game when there is a lose. Previously this code below worked with Python 3.5 but it would abort after it played the sound. I upgraded to python 3.6 and now it just keeps on repeating. How can I play the sound until the end? import pygame def sound(): pygame.mixer.init() sound1 = pygame.mixer.Sound('womp.wav') while True: sound1.play(0) return 回答1: while True is an endless loop: while True: sound1.play(0) The sound will be played continuously. Use

问题 I'm attempting to set up a Discord bot while being relatively new to discord.py (and in reality, Python 3). I want to add the command "greet", which will prompt the user to say "hello" to it. It only responds to "hello", however, when I want it to respond to both "hello" and "Hello". The only things I could think about fixing it was placing them in an or statement, which in theory should've made Python 3 and the bot choose between the two responses (as shown below). @client.event async def on

问题 I'm trying to install geopandas on my laptop, a Windows 10 version 1709 machine. After executing the pip install geopandas command, I'm getting the message: command python setup.py egg_info failed with error code 1. I already tried to upgrade pip and setuptools, but still no success. I installed Python 3.6. 回答1: Assuming you got something like this error: File "C:\Users\Simon\Anaconda3\lib\site-packages\setuptools\msvc.py", line 848, in __init__ raise distutils.errors.DistutilsPlatformError

问题 I'm using APScheduler(3.5.3) to run three different jobs. I need to trigger the second job immediately after the completion of first job. Also I don't know the completion time of first job.I have set trigger type as cron and scheduled to run every 2 hours. One way I overcame this is by scheduling the next job at the end of each job. Is there any other way we can achieve it through APScheduler? 回答1: This can be achieved using scheduler events. Check out this simplified example adapted from the
