can we execute mutiple python scripts from same interpreter

Question

Hi,

I have a python script, which is executing again 4-5 python scripts. For performance reasons i want to use same interpreter for executing all the script.

Is it Possible to do that, if yes please help me out.

Thanks

Kamal

Answer 1

The currently executing interpreter is available in sys.executable. You can just pass that explicitly to subprocess.Popen as the first argument, or pass it as the 'executable' argument.

Answer 2

The obvious solution (which may require a little tweaking) is to just call the main function of each script from a master script. E.g., if script1.py contains:

#!/usr/bin/python
def main():
  // Do something
if __name__ == "__main__":
   main()

put in master.py

#!/usr/bin/python
import script1
def main():
  script1.main()

if __name__ == "__main__":
  main()

You can continue this pattern for as many scripts as you want.

Answer 3

Maybe you're looking for the execfile function in Python 2.x.

In Python 3 it was removed, but there are simple alternatives.
