pyyaml - python ordereddict or OrderedDict? -

i'm confused right now. i'm using pyyaml editing yaml files.

data = yaml.load_all(open('testingyaml.yaml'),loader=yaml.roundtriploader) 

my testingyaml.yaml file contains following content:

spring:   profiles: dev   datasource:     url: jdbc:postgresql://127.0.0.1:5432/nfvgrid dns:   enable: false cassandra:   host: 192.168.7.151 

when print data prints following:

ordereddict([('spring', ordereddict([('profiles', 'dev'), ('datasource', ordereddict([('url', 'jdbc:postgresql://127.0.0.1:5432/nfvgrid')]))])), ('dns', ordereddict([('enable', false)])), ('cassandra', ordereddict([('host', '192.168.7.151')]))])

i further want perform operations on ordered dictionary python throws error nameerror: name 'ordereddict' not defined

it's ordereddict somehow pyyaml returns ordereddict. how should solve issue?

you not using pyyaml stated, not have roundtriploader. instead using ruamel.yaml.

this alternative uses own ruamel.ordereddict on python 2 installations, , native collections.ordereddict on python 3. alternative supports operations ordereddict there no reason cannot manipulate it. see documentation.

however, if wish convert 1 other, like:

x = collections.ordereddict(some_ruamel_ordered_dict.items())
