I'm using ruamel.yaml to add an entry to a dictionary: import ruamel.yaml yaml = ruamel.yaml.YAML() yaml.preserve_quotes = True yaml.indent(mapping=2, sequence=4, offset=2) raw = """--- # Some config file.. # This is the main clients config clients: foobar1: name: foo Bar 1 auth: false count: 1290 barboz: name: BarraBoz auth: true count: 19 uids_default: &uids_default - attribute_email: mail datafile: vars1 uids: - <<: *uids_default skip: true - <<: *uids_default issuer: http://foo.bar """ vanhelst = {"adfs": 124423423, "123": "adsfadsfasdf", "name": "Dirk Van helst"} data = yaml.load(raw) data["clients"].insert(len(data["clients"]), "vanhelst", vanhelst) # Write to file with open("/tmp/out.yml", "w") as f: yaml.dump(data, f) That works, the entry is added correctly, the comment is preserved. But it also changes some anchors that are in the file, to add aliases (?) like id001: # Some config file.. # This is the main clients config clients: foobar1: name: foo Bar 1 auth: false count: 1290 barboz: name: BarraBoz auth: true count: 19 vanhelst: adfs: 124423423 '123': adsfadsfasdf name: Dirk Van helst uids_default: - &id001 attribute_email: mail datafile: vars1 uids: - <<: *id001 skip: true - <<: *id001 issuer: http://foo.bar Is there a way to not add those, and not touch the anchors at all?
