1. Treat it like a module:

   import file 
   

   This is good because it's secure, fast, and maintainable. Code gets reused as it's supposed to be done. Most Python libraries run using multiple methods stretched over lots of files. Highly recommended. Note that your import should not include the .py extension at the end.

   import subprocess
   import sys
   
   subprocess.check_call([sys.executable, 'file.py'])
   

   Use when desperate.
