calling python script from another script

Question

i'm trying to get simple python script to call another script, just in order to understand better how it's working. The 'main' code goes like this:

#!/usr/bin/python
import subprocess
subprocess.call('kvadrat.py')

and the script it calls - kvadrat.py:

#!/usr/bin/python
def kvadriranje(x):
    kvadrat = x * x
    return kvadrat

print kvadriranje(5)

Called script works on its own, but when called through 'main' script error occurs:

Traceback (most recent call last):
  File "/Users/user/Desktop/Python/General Test.py", line 5, in <module>
    subprocess.call('kvadrat.py')
  File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 444, in call
  File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 595, in __init__
  File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1106, in _execute_child
OSError: [Errno 2] No such file or directory

Obviously something's wrong, but being a beginner don't see what.

Answer 1

you need to give it the full path to the script that you are trying to call, if you want to do this dynamically (and you're in the same directory), you can do:

import os    
full_path = os.path.abspath('kvadrat.py')
