Answer 1

try these..

import os
print os.environ['USERNAME']

or

os.getlogin()

then save in a variable and use file handling to store it as a text file..

I'm not sure what problem you're trying to solve, but if you want to track changes to source files you should probably use a version control system such as Subversion. In a nutshell, it will track all the changes to your source files and also manage conflicts (when two people try to change a file at the same time).

If you want a general solution you should take pyinotify, which is a wrapper for the Linux kernel's inotify feature (kernel version >= 2.6.13). With it you can register for certain events in the filesystem, like e.g. in the following code:

from pyinotify import WatchManager, ThreadedNotifier, ProcessEvent, EventsCodes

file_to_monitor = "/tmp/test.py"

class FSEventHook(ProcessEvent):
    def __init__(self, watch_path):
        ProcessEvent.__init__(self)

        wm = WatchManager()
        wm.add_watch(watch_path, EventsCodes.ALL_FLAGS['IN_CLOSE_WRITE'], rec=False)
        self.notifier = ThreadedNotifier(wm, self)

    def start(self):
        self.notifier.start()

    def process_IN_CLOSE_WRITE(self, event):
        if os.path.isfile(event.pathname):
            print "%s changed"%pathname

fshook = FSEventHook(file_to_monitor)
fshook.start()

The following events are supported: IN_MOVED_FROM, IN_CREATE, IN_ONESHOT, IN_IGNORED, IN_ONLYDIR, IN_Q_OVERFLOW, IN_MOVED_TO, IN_DELETE, IN_DONT_FOLLOW, IN_CLOSE_WRITE, IN_MOVE_SELF, IN_ACCESS, IN_MODIFY, IN_MASK_ADD, IN_CLOSE_NOWRITE, IN_ISDIR, IN_UNMOUNT, IN_DELETE_SELF, ALL_EVENTS, IN_OPEN, IN_ATTRIB. For each of them you have to implement its own process_XXX() method, which will be called back if the event is triggered.

What you are asking is if you can track who made changes to a file. And that's not a Python question, but a question of the operating system. To be able to track who changed a file, you need to have an auditing system installed. If you use Linux, it has an audit subsystem that you can configure to track this information, I think.
