LowercaseOrderedDict
(*args)[source]¶ Bases:
collections.abc.MutableMapping
,collections.OrderedDict
Ordered dictionary where all strings keys are case insensitive. i.e. keys such as ‘abc’, ‘ABC’, ‘Abc’ all map to the same value. This can be useful for mimicking the storage of FITS headers.

()Methods Documentation
-
clear
() → None. Remove all items from D.¶
-
fromkeys
(S[, v]) → New ordered dictionary with keys from S.¶ If not specified, the value defaults to None.
-
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¶
-
move_to_end
()¶ Move an existing element to the end (or beginning if last==False).
Raises KeyError if the element does not exist. When last=True, acts like a fast version of self[key]=self.pop(key).
-
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[source]¶ as a 2-tuple; but raise KeyError if D is empty.
-
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
