    This is tested with Python 3.4.3 and BigIP 12.1. Did not have 12.0 installation readily available, but it should work the same for you

    from f5.bigip import ManagementRoot
    
     Optional: omit unsecure certificate warnings from output
    import requests
    from requests.packages.urllib3.exceptions import InsecureRequestWarning
    requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
    
    API_ROOT = ManagementRoot("bip-01", "admin", "admin")
    VSERVER_COLLECTION = API_ROOT.tm.ltm.virtuals.get_collection()
    
    for vserver in VSERVER_COLLECTION:
        print(vserver.name)
         Catch an error to avoid a VS with no iRules breaking the script prematurely
        try:
            irules = vserver.rules
        except AttributeError:
            print('- No iRules on this Virtual Server!')
        else:
            for rule in vserver.rules:
                print('-', rule)
    

    Output in test env:

    $ python list_irules.py
    
    vs_0.0.0.0_any
    - No iRules on this Virtual Server!
    vs_test_80
    - /Common/ir_do_nothing
    - /Common/ir_do_nothing_again
    vs_test_443
    - /Common/ir_do_nothing
    - /Common/ir_do_nothing_again
    

    As you can see from the script above, this takes a bit of testing to get the iRules listed. Ofcourse, ideally either the API or SDK should return an empty list if there are no iRules on a Virtual Server, rather than a script-breaking "AttributeError: 'f5.bigip.tm.ltm.virtual.Virtual'>' object has no attribute 'rules'". SDK is a build up on top of a problematic API, so eventually this problem should be addressed by the API developers.
