Sorry, Python doesn't keep the source code in memory. If the game is
still running in the interpreter, you can ask it for the source code
of a particular code object, but it implements this by opening the
source file and reading it in. Since you've overwritten the file, the
source code would be wrong. The best that you could do in this case
would be to disassemble the code objects using the dis.dis() function,
and then try to reverse-engineer the Python code from the byte code.
If the interpreter is no longer running, then there is nothing you can
do.
For the future, I strongly recommend using a version control system,
such as the free and relatively lightweight Mercurial. Then when you
have these kinds of mishaps all you have to do is check the most
recent version of the code out of the repository again. You should of
course continue to create backups as well, in case of more disastrous
events (although memory sticks are far too failure-prone to be
considered a reliable backup solution IMO).
