Yes, you can use os.popen* for example - but what is the point?
You would waste memory and CPU cycles in firing another complete
interpreter environment.

Instead move the commands in the "file" into a function, use
the common pattern:

def main():
    foo..
    bar...

if __name__=='__main__':
     main()

As you see in many modules.

This was you just import the "file" as module in your external method
and call yourmodule.main()

What are bash commands? Builtin commands like if, fi, while, case etc?
Or do you mean just external executables (binaries, scripts)?
And if so, what are they fore? Python is very capable and you can do
most with it as easy/easier then with extra commands.
If not, see above for os.popen and friends.
