This article describes how to sort dictionaries in python. it is a very practical technique and has detailed annotations in the instance, which is easy to understand, for more information about how to sort dictionaries in python, see the following example. Share it with you for your reference.
The specific implementation method is as follows:
Import itertools thekeys = ['B', 'A', 'C'] thevalues = ['BBB ', 'AAA', 'cccccc'] d = dict (itertools. izip (thekeys, thevalues) # create the dictionary print d def sortedDictValue (adict): keys = adict. keys () keys. sort () return map (adict. get, keys) print sortedDictValue (d) import itertoolsthekeys = ['B', 'A', 'C'] thevalues = ['BBB ', 'AAA ', 'cccc'] def sortedDictValue (adict): # use a custom sorting function to obtain the dictionary keys () and sort the keys, finally, take the dictionary value keys = adict based on the sorted keys. keys () keys. sort () return map (adict. get, keys) # Here is the only difference. here, the built-in map function is called to call adict for each project in keys. get function, returns a list of print sortedDictValue (d) # print the same result
The program running result is:
{'A': 'AAA', 'C': 'cccc', 'B': 'BBB'} ['AAA', 'BBB ', 'cccc'] ['AAA', 'BBB ', 'cccccc']
I hope this article will help you learn Python programming.
