Example 1: python find the key with max value
a_dictionary = {"a": 1, "b": 2, "c": 3}
max_key = max(a_dictionary, key=a_dictionary.get)
print(max_key)
Example 2: max of a dict
dic={0: 1.4984074067880424, 1: 1.0984074067880423, 2: 1.8984074067880425, 3: 2.2984074067880425, 4: 2.2984074067880425}
max_value = max(dic.values())
max_keys = [k for k, v in dic.items() if v == max_value]
print(max_value, max_keys)
Example 3: find the max value in dictionary python
my_dict = {'a': 5, 'b': 10, 'c': 6, 'd': 12, 'e': 7}
max(my_dict, key=my_dict.get)
Example 4: python get min max value from a dictionary
d = {'A': 4,'B':10}
min_v = min(zip(d.values(), d.keys()))
max_v = max(zip(d.values(), d.keys()))
Example 5: python max key dictionary key getter
from operator import itemgetter
items = [
{'a': 1, 'b': 99},
{'a': 2, 'b': 88},
{'a': 3, 'b': 77},
]
print(max(items, key=itemgetter('a')))
print(max(items, key=itemgetter('b')))
Example 6: get max n values in dict py
import heapq
from operator import itemgetter
n = 3
items = {'a': 7, 'b': 12, 'c': 9, 'd': 0, 'e': 24, 'f': 10, 'g': 24}
topitems = heapq.nlargest(n, items.items(), key=itemgetter(1))
topitemsasdict = dict(topitems)
