title: Using a Python subprocess call to invoke a Python script
body: <p>I have a Python script that needs to invoke another Python script in the same directory. I did this:</p>
  
  <pre><code>from subprocess import call
  call('somescript.py')
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>call('somescript.py')
  File "/usr/lib/python2.6/subprocess.py", line 480, in call
  return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.6/subprocess.py", line 633, in __init__
  errread, errwrite)
  File "/usr/lib/python2.6/subprocess.py", line 1139, in _execute_child
  
  raise child_exception
  OSError: [Errno 2] No such file or directory
  </code></pre>
  
  <p>I have the script somescript.py in the same folder though. Am I missing something here?</p>
