Copy all keys (or values, or both, depending on what you need), then iterate over those, You can use

Example_snippet/controller/utility/_iterated.js/ >>> mydict {'four': 4, 'three'. . .
>>> mydict {
   'four': 4,
   'three': 3,
   'one': 1
}

>>>
for k in list(mydict.keys()):
   ...
   if mydict[k] == 3:
   ...del mydict[k]
   ...
   >>>
   mydict {
      'four': 4,
      'one': 1
   }
Step 2 continued with >>> mydict = {'one': 1, 'two':. . .
>>> mydict = {'one': 1, 'two': 2, 'three': 3, 'four': 4}
>>> for k, v in mydict.iteritems():
...    if k == 'two':
...        del mydict[k]
...
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
RuntimeError: dictionary changed size during iteration
Step 3 continued with >>> for k in mydict.keys(): ... . .
>>>
for k in mydict.keys():
   ...
   if k == 'two':
   ...del mydict[k]
   ...
   >>>
   mydict {
      'four': 4,
      'three': 3,
      'one': 1
   }
Step 4 continued with >>> for k, v in mydict.items(). . .
>>>
for k, v in mydict.items():
   ...
   if v == 3:
   ...del mydict[k]
   ...
   >>>
   mydict {
      'four': 4,
      'one': 1
   }
