Installation
$ pip install pydottieor
$ pip3 install pydottieBasic Usage
Get
Gets nested value, or None if unreachable, or a default value if passed.
# PyDottie
import pydottie
values = {
'some': {
'nested': {
'key': 'foobar',
}
},
'some.dot.included': {
'key': 'barfoo'
}
}
# returns 'foobar'
print(pydottie.get(values, 'some.nested.key'))
# returns None
print(pydottie.get(values, 'some.undefined.key'))
# returns 'defaultval'
print(pydottie.get(values, 'some.undefined.key', 'defaultval'))
# returns 'barfoo'
print(pydottie.get(values, ['some.dot.included', 'key']))Set value
Sets nested value, creates nested structure if needed.
# PyDottie
import pydottie
values = {
'some': {
'nested': {
'key': 'foobar',
}
},
'some.dot.included': {
'key': 'barfoo'
}
}
pydottie.set_value(values, 'some.nested.value', 'someValue')
pydottie.set_value(values, ['some.dot.included', 'value'], 'someValue')
# force overwrite defined non-object keys into objects if needed
pydottie.set_value(values, 'some.nested.object', 'someValue', force=True)Transform object
Transform dictionary from keys with dottie notation to nested objects.
# PyDottie
import pydottie
values = {
'user.name': 'Gummy Bear',
'user.email': 'gummybear@candymountain.com',
'user.professional.title': 'King',
'user.professional.employer': 'Candy Mountain'
};
