  2. It is not possible to sort a dictionary, only to get a representation of a dictionary that is sorted. Dictionaries are inherently orderless, but other types, such as lists and tuples, are not. So you need an ordered data type to represent sorted values, which will be a list—probably a list of tuples.

  3. A simple way I found to sort a dictionary is to create a new one, based on the sorted key:value items of the one you're trying to sort. If you want to sort dict = {} , retrieve all its items using the associated method, sort them using the sorted() function then create the new dictionary.

  4. Python has supported the key= for .sort since 2.4, that is year 2004, it does the Schwartzian transform within the sorting code, in C; thus this method is useful only on Pythons 2.0-2.3. all of which are more than 12 years old.

  5. Now that the insertion order of Python dictionaries is guaranteed starting in Python 3.7 (and in CPython 3.6), what is the best/fastest way to sort a dictionary - both by value and by key? The most obvious way to do it is probably this:

  6. If you want to deal with ordering you'll need to convert the dictionary to a list. a = list(a) # keys in list a = a.keys() # keys in list a = a.values() # values in list a = a.items() # tuples of (key,value) in list Now you can sort the list as normal, e.g., a.sort() and reverse it as well, e.g., a.reverse()

  7. sorting dictionary python 3 - Stack Overflow

    stackoverflow.com/questions/11089655

    How to sort by key in Python 3.7 The big change in Python 3.7 is that the dictionaries are now ordered by default . You can generate sorted dict using dict comprehensions.

  8. dictionary - sort dict by value python - Stack Overflow

    stackoverflow.com/questions/16772071

    I also think it is important to note that Python dict object type is a hash table (more on this here), and thus is not capable of being sorted without converting its keys/values to lists.

  9. python - Sort dict by highest value? - Stack Overflow

    stackoverflow.com/questions/20304824

    It uses the built-in function sorted (with reverse=True to get highest to lowest), and the key argument is a function that sets the sort key. In this case it's a lambda that fetches the corresponding dict value, but it can be pretty much anything.

  10. If you want to sort by the order that items were inserted instead of of the order of the keys, you should have a look to Python's collections.OrderedDict. (Python 3 only) (Python 3 only) Share

  11. How to sort dictionary by key in numerical order Python

    stackoverflow.com/questions/22264956

    So you could first sort your dictionary (as above) and then create an OrderedDict from the sorted (key, value) pairs: sorted_docs_info = collections.OrderedDict(sorted(docs_info.items())) Share
