Certainly you can script it. Write a tiny shell script (named "mygensolve.sh" 
for the sake of example).  Example (untested):

  #!/bin/sh
  python NFV_nw_eu_v3_14_1_15.py --output eu_v3_14_1_15 --demand demands_v3_21_1_15.xml --xml nobel-eu.xml
  python NFV_v3_7_10_14.py -l log --lp --xml eu_v3_14_1_15.xml

Either make it executable ("chmod +rx mygensolve.sh") and run it like this:

  ./mygensolve.sh

or don't bother, and run it in an analogous fashion to your python commands:

  sh mygensolve.sh

There are multiple paths forward from here if you have many runs with filenames 
which can be enurated somehow.
