easybuild.tools.ordereddict module

Module provided an ordered dictionary class.

author:Raymond Hettinger
class easybuild.tools.ordereddict.OrderedDict(*args, **kwds)

Bases: dict

Dictionary that remembers insertion order

clear() → None. Remove all items from od.
copy() → a shallow copy of od
classmethod fromkeys(S[, v]) → New ordered dictionary with keys from S

and values equal to v (which defaults to None).

items() → list of (key, value) pairs in od
iteritems()

od.iteritems -> an iterator over the (key, value) items in od

iterkeys() → an iterator over the keys in od
itervalues()

od.itervalues -> an iterator over the values in od

keys() → list of keys in od
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), return and remove a (key, value) pair.

Pairs are returned in LIFO order if last is true or FIFO order if false.

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

If E is a dict instance, does: for k in E: od[k] = E[k] If E has a .keys() method, does: for k in E.keys(): od[k] = E[k] Or if E is an iterable of items, does: for k, v in E: od[k] = v In either case, this is followed by: for k, v in F.items(): od[k] = v

values() → list of values in od
viewitems() → a set-like object providing a view on od's items
viewkeys() → a set-like object providing a view on od's keys
viewvalues() → an object providing a view on od's values
