Python equivalent of "logname" command

[Jason Hsu]

In GNU Bash, the "logname" command returns your username, even if you
invoke the command as root. (The "whoami" command returns "root" if
you invoke it as root.)

What's the Python equivalent of "logname"?

[Matt Anderson]

What do you mean "as root"? Sudo, su, logging in directly on console?

Try os.getuid() and os.geteuid() -- do they return different things? Do they return the same thing, neither of which is your normal userid?

You can turn a UID into a name with pwd.getpwuid(); returns a structure, but the pw_name field on the structure should be a user name.
