Getting started

First import module:

>>> import dicttools

Now you can use dicttools functions. For example if you want to merge dict type:

>>> dicttools.merge({'a': 1}, {'b': 2}, {'c': 3})
{'a': 1, 'c': 3, 'b': 2}

To select items from dict:

>>> dicttools.select({'a': 1, 'c': 3, 'b': 2}, 'a', 'b')
{'a': 1, 'b': 2}

Also you can create FrozenDict:

>>> frozen = dicttools.FrozenDict(a=1, b=2)
>>> frozen
FrozenDict({'a': 1, 'b': 2})

The FrozenDict is immutable, so it cannot be changed:

>>> frozen['c'] = 3
Traceback (most recent call last):
  File "<input>", line 1, in <module>
TypeError: 'FrozenDict' object does not support item assignment

But work just like dict:

>>> frozen['a']
1
>>> list(frozen.items())
[('a', 1), ('b', 2)]
