[ins] In [1]: from os import system

[ins] In [2]: system('./test.py')
hallo world
Out[2]: 0

[ins] In [3]: from subprocess import call

[ins] In [4]: call('./test.py')
hallo world
Out[4]: 0

In the first call you call ’.Test.py’
In the second call you call ’test.py’

“supprocess” doesn’t exist

How about

subprocess.call(‘\.Test.py’)

Or

subprocess.call([‘\.Test.py’])

Whereas the later makes more sense if you want to pass arguments to Test.py
