#82208 — [newbie] how to make program suggest to install missing modules

I'd like to add the following to a python-program:

when a module (take rtlsdr as an example) is not installed on the system I'd 
like to ask the program something like:

module rtlsdr is missing, shall I install it? y or n
if n -->sorry but then I can't run this program and quit program
if y -->execute this command:
os.system(sudo pip install pyrtlsdr)

continue program

can anyone here show me how to perform this properly?

thanks in advance
hugo

Hint:

try:
    import someModule
except ImportError:
    print "Module is missing"
    # handle it!

Just make sure to attempt to import it again after making the call to pip to 
install it.
