You can't, really. The 'alias' command is a shell built-in, not an external
command, so you can't meaningfully run it from a Python script (and any
aliases defined in your shell will probably not be available to Python).
Matters are complicated a little bit because when you use os.popen(),
your command line is actually passed to *a* shell, usually /bin/sh, so
the final command line looks like this:
/bin/sh -c 'alias'
However, even if /bin/sh is actually bash, dotfiles such as .profile and
.bashrc aren't read when using the '-c' option.
If you really want to do something to your bash aliases with python, you
could pipe them into a python command:
$ alias | python myscript.py
