python sorted dictionary multiple keys

mylist = sorted(mylist, key=itemgetter('name', 'age'))
mylist = sorted(mylist, key=lambda k: (k['name'].lower(), k['age']))
mylist = sorted(mylist, key=lambda k: (k['name'].lower(), -k['age']))

python sort multiple keys

records.sort(
  key = lambda l: (l[0], l[2])
)

sorted multiple keys python

a_list = ["aaa", "cc", "bb"]

new_list = sorted(a_list, key=lambda x: (len(x), x))
#Sort by length then alphabetically

print(new_list)
#OUTPUT
#>>['bb', 'cc', 'aaa']

python sort based on multiple keys

>>> def multisort(xs, specs):
...     for key, reverse in reversed(specs):
...         xs.sort(key=attrgetter(key), reverse=reverse)
...     return xs
