Thanks for the suggestions, you can see here below what I came up with.
All suggestions/corrections welcome:
#!/usr/bin/env python
import imp
import os
import sys
try:
imp.find_module('rtlsdr')
except ImportError:
print('Module rtlsdr is missing')
print("I'll try to install it")
os.system('sudo pip install pyrtlsdr')
try:
imp.find_module('rtlsdr')
except ImportError:
sys.exit('Sorry could not install module rtlsdr, contact your
local Python-guru')
import rtlsdr
print('Module rtlsdr succesfully imported')
