Python - How to detect when user closes a console application via "X" button -

I currently have a console based Python program running under Windows. This program keeps most of its data in memory and periodically saves data to disk or when the user has a keyboard interrupt ( Ctrl + C ) The application has stopped.

The problem I have is that when a user hits the "X" button at the top right of the console window, the session stops and the data is lost in memory. What I want is an event / signal or hook, so that I can clear the memory before closing.

I hope to do this without any external libraries, though it is not possible I still want to know how it can be done.

in the window

If you are using pywin32, you close the console An event can happen before it happens, I am not sure whether it will tell you who is shutting it down, but it may have shown you half way. You can also check them:

  import atom, OS atexit.register (lambda: OSSystem ("pause"))    for those Those who come on it and use Linux ...    The SIGHUP signal is thrown when the import signal signal is off (signal is hanging).     Terminal session closes before the program closes, when it indicates: # Indicator (signal.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
