Python 使用defaultdict时需要忽略yaml输出中的值
以下代码段:Python 使用defaultdict时需要忽略yaml输出中的值,python,dictionary,yaml,Python,Dictionary,Yaml,以下代码段: import yaml import collections def hasher(): return collections.defaultdict(hasher) data = hasher() data['this']['is']['me'] = 'test' print yaml.dump(data) 这将返回: !!python/object/apply:collections.defaultdict args: [&id001 !!python/n
import yaml
import collections
def hasher():
return collections.defaultdict(hasher)
data = hasher()
data['this']['is']['me'] = 'test'
print yaml.dump(data)
这将返回:
!!python/object/apply:collections.defaultdict
args: [&id001 !!python/name:__main__.hasher '']
dictitems:
this: !!python/object/apply:collections.defaultdict
args: [*id001]
dictitems:
is: !!python/object/apply:collections.defaultdict
args: [*id001]
dictitems: {me: test}
我将如何删除:
!!python/object/apply:collections.defaultdict
[*id001]
最终目标是:
this:
is:
me: "test"
感谢您的帮助 您需要在
yaml
模块中注册重新输入:
from yaml.representer import Representer
yaml.add_representer(collections.defaultdict, Representer.represent_dict)
现在yaml.dump()
将defaultdict
对象视为dict
对象:
>>> print yaml.dump(data)
this:
is: {me: test}
>>> print yaml.dump(data, default_flow_style=False)
this:
is:
me: test
