container

class zfit.util.container.DotDict[source]

Bases: dict

dot.notation access to dictionary attributes

clear() → None. Remove all items from D.
copy() → a shallow copy of D
fromkeys()

Create a new dictionary with keys from iterable and values set to value.

get()

Return the value for key if key is in the dictionary, else default.

items() → a set-like object providing a view on D's items
keys() → a set-like object providing a view on D's keys
pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised

popitem() → (k, v), remove and return some (key, value) pair as a

2-tuple; but raise KeyError if D is empty.

setdefault()

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) → None. Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() → an object providing a view on D's values
zfit.util.container.convert_to_container(value: Any, container: Callable = <class 'list'>, non_containers=None, convert_none=False) → Union[None, Iterable][source]

Convert value into a container storing value if value is not yet a python container.

Parameters
  • value (object) –

  • container (callable) – Converts a tuple to a container.

  • non_containers (Optional[List[Container]]) – Types that do not count as a container. Has to be a list of types. As an example, if non_containers is [list, tuple] and the value is [5, 3] (-> a list with two entries),this won’t be converted to the container but end up as (if the container is e.g. a tuple): ([5, 3],) (a tuple with one entry).

Returns:

zfit.util.container.is_container(obj)[source]

Check if object is a list or a tuple.

Parameters

() (obj) –

Returns

True if it is a container, otherwise False

Return type

bool
