python-3.4

问题 I want to show a notification in my python3 program telling the user that there is a new version available. That part is easy and there are lots of examples (like this) to show a notification in windows. But I'd also like that when the user clicks the notification (instead of closing it) to open a window with more info about the update (show changelog, download button, whatever...). Is it possible to add an onClick handler to the notification? I've been searching a few hours but I can't find

问题 I am trying to wait for a song to finish to play the next song. I am running python 3.4 on windows but am trying to be able to use it on Linux ( raspberry pi ). I have used the command subprocess.call([PLAYER, SONG]) to open the mp3 file. It plays in vlc and then stops. I know that I have not incorporated anything for the program to tell python when its finished. That's where you guys come in. I want to find a command that will wait until the song has finished and when the song is finished,

问题 How could I have a user input something like Blah Blah [1-30] Blah and then parse it to get a list like so: [ 'Blah Blah 1 Blah', 'Blah Blah 2 Blah', etc... 'Blah Blah 30 Blah', ] 回答1: Use regex. First find the start and end points ,specified by [a-b] . Then loop them, and replace these brackets by the increasing number: import re expr = input('Enter expression: ') # Blah Blah [1-30] Blah start, end = map(int, re.findall('(\d+)-(\d+)', expr)[0]) my_list = [re.sub('\[.*\]', str(i), expr) for i

问题 I'm trying to understand how does asyncio work. In my scenario client makes a tcp connection to the server, sends a login string, if authenticated - receives a stream of chars. Finally on KeyboardInterrupt sends logoff string to the server and hapilly disconnects. Currently I'm stuck on the final part as my logoff method/task is destroyed before it has a chance to complete. ^CTask was destroyed but it is pending! source_traceback: Object created at (most recent call last): File "tst.py", line
