Types

PyDictItemView[K; V] = object of PyDictView
  mapping*: PyDict[K, V]
Source   Edit   
PyDictKeyView[T] = object of PyDictView
  mapping*: PyDict[T, auto]
Source   Edit   
PyDictValueView[T] = object of PyDictView
  mapping*: PyDict[auto, T]
Source   Edit   
PyDictView = object of RootObj
Warning: currently mapping attr is dict itself, i.e. modifiable

func pop[K, V](self: PyDict[K, V]; key: K; default: V): V
Source   Edit   
func popitem[K, V](self: PyDict[K, V]): (K, V)

Source   Edit   
func values[K, V](self: PyDict[K, V]): PyDictValueView[V]
Source   Edit   
func `|`(a, b: PyDict): PyDict
Python-like merge dict operator, a new dict is created from a and b, keys in the second operand override keys in the first operand Source   Edit   
proc `|=`(a, b: PyDict)
Python-like in-place dict update operator. b is added into a, keys in b override same keys from a Source   Edit  

Iterators

iterator items[K, V](self: PyDict[K, V]): (K, V)
Source   Edit   
iterator iter[K, V](self: PyDict[K, V]): K
Warning: Nim's for stmt calls items implicitly, instead of iter so beware to always write iter for dict in for loop

Example:

let d = dict(a=1)
for i in iter(d):
  assert i == "a"
for i in d:
  assert i[0] == "a" and i[1] == 1
