Retrieving YAML parameters at run time in App Engine (Python)

Question

Is it possible to programmatically get any of the YAML parameters at runtime? Are they stored somewhere in the environment?

A good example would be to automatically detect the version of the application and add it as a comment on the landing HTML page.

Answer 1

No, but some data is available from os.environ - for example, os.environ['APPLICATION_ID']and os.environ['CURRENT_VERSION_ID'].

Answer 2

( , CGI WSGI). app.yaml , app.yaml (, my.yaml )

import yaml

...

data = yaml.load(open('my.yaml', 'rb'))

data.

Answer 3

In PyYAML, the file __init__.pyin the yaml folder has a global variable __version__, so

#import yaml
print yaml.__version__
