title: Save variable value in python
body: <p>Is there a way to SAVE the value of a variable (say an integer) in python? 
  My problem involves calling (entering and exiting) multiple times the same python script (python file, not python function) which in the end creates a txt file. I'd like to name the txt files depending on the number of times the python code was called: txt1.txt,..., txt100.txt for example.</p>
  
  <p>EDIT:
  The question is not related with the SAVE parameter in fortran. My mistake.</p>
