Change environment variables persistently with Python -


is possible using python 3.5 create , update environment variables in windows , linux persisted?

at moment use this:

import os os.environ["my_variable"] = "true"

however seems if not "store" environment variable persistently.

i'm speaking linux here, not sure windows.

environment variables don't work way. part of process (which modify changing os.environ), , propagate child processes of process (and children obviously). in-memory only, , there no way "set , persist" them directly.

there several configuration files allow set environment on more granular basis. these read various processes, , can system-wide, specific user, specific shell, particular type of process etc.

some of them are:

  • /etc/environment system-wide variables
  • /etc/profile shells (and children)
  • several other shell-specific files in /etc
  • various dot-files in user's home directory such .profile, .bashrc, .bash_profile, .tcshrc , on. read shell's documentation.
  • i believe there various ways configure environment variables launched guis (e.g. gnome panel or that).

most of time you'll want set environment variables current user only. if care shells, append them ~/.profile in format:

name="value"

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
