用于处理邪恶/复杂数据的人类的python字典。
python-benedict的Python项目详细描述
Python本尼迪克特
用于处理邪恶/复杂数据的人类的python字典。
功能
- 完整的keypath支持（默认使用点语法）
- 许多utility和parse方法根据需要检索数据（下面列出的所有方法）
- 在返回值（它们接受benedict casting）
- 简单的I/O操作最常用的格式是：
base64，json，query-string，toml，yaml，xml
要求
- python 2.7、3.4、3.5、3.6、3.7
安装
- 运行
pip install python-benedict
测试
- 运行
tox/python setup.py test
用法
^ {CD11>}是一个^ {< CD1>}子类，因此可以将其用作普通字典^ {EM1}$（您可以只投一个现有的DICT）
导入
frombenedictimportbenedict
初始值
创建新实例：
d=benedict()
…或铸造现有的^ {< CD1> }：
d=benedict(existing_dict)
如果现有的DICT键包含键路径分隔符，将引发A^ {
在这种情况下，您应该使用custom keypath separator。
键槽
.是默认的密钥路径分隔符。
d=benedict()# set values by keypathd['profile.firstname']='Fabio'd['profile.lastname']='Caccamo'print(d)# -> { 'profile':{ 'firstname':'Fabio', 'lastname':'Caccamo' } }print(d['profile'])# -> { 'firstname':'Fabio', 'lastname':'Caccamo' }# check if keypath exists in dictprint('profile.lastname'ind)# -> True# delete value by keypathdeld['profile.lastname']
自定义键槽分隔符
可以在构造函数中自定义传递keypath_separator参数的keypath分隔符。
d=benedict(existing_dict,keypath_separator='/')

键槽方法
关键路径
# Return a list of all keypaths in the dict.d.keypaths()
实用方法
关键路径
这些方法是常用的工具，可以加快你的日常工作。
清洁
# Clean the current dict removing all empty values: None, '', {}, [], ().# If strings, dicts or lists flags are False, related empty values will not be deleted.d.clean(strings=True,dicts=True,lists=True)
深度复制
# Return a deepcopy of the dict.d.deepcopy()
转储
# Return a readable representation of any dict/list.s=benedict.dump(d.keypaths())print(s)
倾倒物品
# Return a readable representation of the dict for the given key (optional).s=d.dump_items(key=None)print(s)
过滤器
# Return a filtered dict using the given predicate function.# Predicate function receives key, value arguments and should return a bool value.predicate=lambdak,v:visnotNoned.filter(predicate)
移除
# Remove multiple keys from the dict.d.remove(['firstname','lastname','email'])
子集
# Return a dict subset for the given keys.d.subset(['firstname','lastname','email'])
分析方法
这些方法是get方法的包装器，它们解析试图以预期类型返回的数据。
获取布尔值
# Get value by key or keypath trying to return it as bool.# Values like `1`, `true`, `yes`, `on`, `ok` will be returned as `True`.d.get_bool(key,default=False)
获取布尔列表
# Get value by key or keypath trying to return it as list of bool values.# If separator is specified and value is a string it will be splitted.d.get_bool_list(key,default=[],separator=',')

# Get value by key or keypath trying to return it as dict.# If value is a json string it will be automatically decoded.d.get_dict(key,default={})
获取电子邮件
# Get email by key or keypath and return it.# If value is blacklisted it will be automatically ignored.# If check_blacklist is False, it will be not ignored even if blacklisted.d.get_email(key,default='',options=None,check_blacklist=True)

django
benedict在django视图中也非常有用：
params=benedict(request.GET.items())
