How to convert an OrderedDict into a regular dict in python3

Question

I am struggling with the following problem  I want to convert an OrderedDict like this   OrderedDict    method    constant      data    1 225       into a regular dict like this     method    constant    data  1 225    because I have to store it as string in a database  After the conversion the order is not important anymore  so I can spare the ordered feature anyway   Thanks for any hint or solutions   Ben

It is easy to convert your OrderedDict to a regular Dict like this   dict OrderedDict    method    constant      data    1 225        If you have to store it as a string in your database  using JSON is the way to go   That is also quite simple  and you don t even have to worry about converting to a regular dict   import json d   OrderedDict    method    constant      data    1 225     dString   json dumps d    Or dump the data directly to a file   with open  outFile txt   w   as o      json dump d  o

Its simple way    gt  gt import json   gt  gt from collection import OrderedDict   gt  gt json dumps dict OrderedDict    method    constant      data    1 225

If you are looking for a recursive version without using the json module   def ordereddict to dict value       for k  v in value items            if isinstance v  dict               value k    ordereddict to dict v      return dict value

If somehow you want a simple  yet different solution  you can use the    dict  syntax   from collections import OrderedDict  ordered   OrderedDict    method    constant      data    1 225     regular      ordered

Here is what seems simplest and works in python 3 7 from collections import OrderedDict  d   OrderedDict    method    constant      data    1 225     d2   dict d     Now a normal dict  Now to check this   gt  gt  gt  type d2   lt class  dict  gt   gt  gt  gt  isinstance d2  OrderedDict  False  gt  gt  gt  isinstance d2  dict  True  NOTE  This also works  and gives same result -  gt  gt  gt     d    method    constant    data    1 225    gt  gt  gt     d     d2 True  As well as this -  gt  gt  gt  dict d    method    constant    data    1 225    gt  gt  gt  dict d        d  True  Cheers

A version that handles nested dictionaries and iterables but does not use the json module  Nested dictionaries become dict  nested iterables become list  everything else is returned unchanged  including dictionary keys and strings bytes bytearrays   def recursive to dict obj       try          if hasattr obj   quot split quot         is string-like             return obj         elif hasattr obj   quot items quot       is dict-like             return  k  recursive to dict v  for k  v in obj items            else                           is iterable             return  recursive to dict e  for e in obj      except TypeError                   return everything else         return obj

gt  gt  gt  from collections import OrderedDict  gt  gt  gt  OrderedDict    method    constant      data    1 225     OrderedDict    method    constant      data    1 225      gt  gt  gt  dict OrderedDict    method    constant      data    1 225        data    1 225    method    constant    gt  gt  gt    However  to store it in a database it d be much better to convert it to a format such as JSON or Pickle  With Pickle you even preserve the order

Even though this is a year old question  I would like to say that using dict will not help if you have an ordered dict within the ordered dict  The simplest way that could convert those recursive ordered dict will be  import json from collections import OrderedDict input dict   OrderedDict    method    constant      recursive   OrderedDict    m    c        output dict   json loads json dumps input dict   print output dict
