Python: sort an array of dictionaries with custom comparator?

Question

I have the following Python array of dictionaries:

myarr = [ { \'name\': \'Richard\', \'rank\': 1 },
{ \'name\': \'Reuben\', \'rank\': 4 },
{ \'name\': \'Reece\'         


        

Answer 1

You can use function in key param:

for ass sorting:

sorted_master_list = sorted(myarr, key=lambda x: x.get('rank'))

or to desc:

sorted_master_list = sorted(myarr, key=lambda x: -x.get('rank'))

Also you can read about sorted function here http://wiki.python.org/moin/HowTo/Sorting
