Bases: MutableMapping

Contains metadata that may be assigned to a dataset attribute. Is stored in the HDF5 object’s attrs dict.

\*\*kwargs

Extra metadata to include. Must be a string, number or numpy array

py_type

String representation of this attribute's python type.

bind_key(_AttributeInfo__name)

Returns __name dot-prefixed with attrs_namespace.

clear()

get(k[,d])

items()

keys()

load(info)

Inserts the values set in info into this instance.

pop(k[,d])

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

popitem()

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

save(info)

Inserts the values set in this instance into info.

setdefault(k[,d])

update([E, ]**F)

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

values()

classmethod bind_key(_AttributeInfo__name)[source]

Returns __name dot-prefixed with attrs_namespace.

clear() None.  Remove all items from D.
get(k[, d]) D[k] if k in D, else d.  d defaults to None.
items() a set-like object providing a view on D's items
keys() a set-like object providing a view on D's keys
load(info)[source]

Inserts the values set in info into this instance.

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.

save(info)[source]

Inserts the values set in this instance into info.

setdefault(k[, d]) D.get(k,d), also set D[k]=d if k not in D
update([E, ]**F) None.  Update D from mapping/iterable E and F.

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

values() an object providing a view on D's values
