Messing with online python playgrounds

NOTE: ONLINE PYTHON PLAYGROUNDS PROBABLY RUN ON DOCKER CONTAINERS OR SANDBOXES OR process lacks root privileges SO NO REAL HARM CAN BE DONE WITH THIS

Situation:

All occurrences of this text 'system' will be stripped from the code written here when processed by the client or server. There for strings will be stripped of the word 'system' and import statements will throw errors

This is to prevent access to os.system which allows us to run shell commands

Examples: a- import system from os # will be converted to: import from os b- import os.system will be converted to: import os. c- modulelib.import_module('os.system') to: modulelib.import_module('os.') d- string '12system12' # will be converted to: 1212

Try a, b, c by youselves because if I add them they will break the script

Solution:

Create an algorithm that during_runtime joins an array of chars and split them by using a designated char to signal that the current word is complete: i.e: ['o', 's', '.', 's', 'y', 's', 't', 'e', 'm'] should be turned into strings "os" and "system" during runtime
use the setattr() build in function to extract the 'system' method from the os module during runtime

How to use

just copy and paste in online editor and modify the shell commands at the end of the file
