That is how OrderedDict “solves your problem”.  But, a few points worth reemphasizing:<\/p>\n
    \n
  1. Dicts are unordered.  You can’t “sort them”, only operate on their keys and values.<\/li>\n
  2. OrderedDicts remember the order that items were added.<\/li>\n
  3. It sounds like you are trying to print to a file something that looks like dict syntax.  If you do that and read the dict into python at some point, it will become an unordered object (a dict) again<\/em>. <\/li>\n
  4. It is not super clear what “your problem” is.  What is the desired end state; printing a string that reads like dict syntax?  Making something that has the accessor methods that dicts do?  Clarifying what exactly you want (in terms of performance) would be helpful.<\/li>\n
  5. The code above has O(n**2) complexity.  Don’t use it on big things. <\/li>\n<\/ol><\/div>\n
