由 做~自己de王妃 提交于 2019-11-26 18:03:44
问题 I see a lot of connections are open and remain idle for a long time, say 5 minutes. Is there any solution to terminate / close it from server without restarting the mysql service? I am maintaining a legacy PHP system and can not close the connections those are established to execute the query. Should I reduce the timeout values in my.cnf file those defaults to 8 hours? # default 28800 seconds interactive_timeout=60 wait_timeout=60 回答1: Manual cleanup: You can KILL the processid. mysql> show

When running a python script in IDLE, is there a way to pass in command line arguments (args)?

问题 I'm testing some python code that parses command line input. Is there a way to pass this input in through IDLE? Currently I'm saving in the IDLE editor and running from a command prompt. I'm running Windows. 回答1: It doesn't seem like IDLE provides a way to do this through the GUI, but you could do something like: idle.py -r scriptname.py arg1 arg2 arg3 You can also set sys.argv manually, like: try: __file__ except: sys.argv = [sys.argv[0], 'argument1', 'argument2', 'argument2'] (Credit http:/

Any way to clear python's IDLE window?

I know there's a similar topic about python console, but I do not know if they are the same. I tried system("clear") and it didn't work here. How do I clear python's IDLE window? The "cls" and "clear" are commands which will clear a terminal (ie a DOS prompt, or terminal window). From your screenshot, you are using the shell within IDLE, which won't be affected by such things. Unfortunately, I don't think there is a way to clear the screen in IDLE. The best you could do is to scroll the screen down lots of lines, eg: print "\n" * 100 Though you could put this in a function: def cls(): print "

Python: Why is IDLE so slow?

问题 IDLE is my favorite Python editor. It offers very nice and intuitive Python shell which is extremely useful for unit-testing and debugging, and a neat debugger. However, code executed under IDLE is insanely slow. By insanely I mean 3 orders of magnitude slow: bash time echo "for i in range(10000): print 'x'," | python Takes 0.052s, IDLE import datetime start=datetime.datetime.now() for i in range(10000): print 'x', end=datetime.datetime.now() print end-start Takes: >>> 0:01:44.853951 Which is

问题 How do I run a python script from within the IDLE interactive shell? The following throws an error: >>> python helloworld.py SyntaxError: invalid syntax 回答1: Python2 Built-in function: execfile execfile('helloworld.py') It normally cannot be called with arguments. But here's a workaround: import sys sys.argv = ['helloworld.py', 'arg'] # argv[0] should still be the script name execfile('helloworld.py') Python3 : alternative to exefile: exec(open('helloworld.py').read()) See https:/

Can multiprocessing Process class be run from IDLE

由 空扰寡人 提交于 2019-11-26 07:49:02
问题 A basic example of multiprocessing Process class runs when executed from file, but not from IDLE. Why is that and can it be done? from multiprocessing import Process def f(name): print(\'hello\', name) p = Process(target=f, args=(\'bob\',)) p.start() p.join() 回答1: Yes. The following works in that function f is run in a separate (third) process. from multiprocessing import Process def f(name): print('hello', name) if __name__ == '__main__': p = Process(target=f, args=('bob',)) p.start() p.join
