I allso want to now this: "How can I start a python program out of a python program?"

• You can import it. And then just run what you need from the imported module
  

  import mymodule
  
  mymodule.myfunction()

• That being said, there are other ways, one (which is unsafe) is to use exec:
  

  execfile('mymodule.py')

• You can spawn it using os (again not recommended):
  

  import os
  
  os.system('python mymodule.py')

• And finally, save the best for last, use subprocess
  

  import subprocess
  runproc = subprocess.run([python mymodule.py])
  
  
  # if you need to capture output of mymodule use:
  runproc = subprocess.run([python mymodule.py]
      stdout=subprocess.PIPE,
  )
  
  results = runproc()
  print(results)
