title: How to set environment variable value for embedded Python intepreter?
body: <p>I need to pass environment variable value in script which in interpreted in embedded (in iOS app) Python interpreter. I know I can use <code>setenv</code> before <code>Py_Initialize</code>, but it would be available to all the 3rd-party libraries. Is there any possibility to set environment variable value for Python interpret only? Something like <code>Py_SetEnvVar(char *name, char *value)</code> to make it available in python scripts:</p>
  
  <pre><code>os.environ.get('MY_ENV_VAR')
  </code></pre>
