Use response.json() instead of eval()

[mgood]

Requests has a convenient way to parse JSON responses:

http://docs.python-requests.org/en/latest/user/quickstart/#json-response-content

Not only is this easy to use, but it prevents the major security issue of calling eval() on a response from a remote service.

Oh, it seems that you're using the Jenkins "Python" flavored API instead of JSON. I don't see the Jenkins docs mention explicitly what types might be encoded in the Python responses, but if it's equivalent to the JSON types (dict, list, etc) using JSON would be a safer alternative. Or you could possibly use this to safely parse Python's literal types without allowing code execution:
