  • Difficulty Level : Easy
  • Last Updated : 18 May, 2020

Given a dictionary, the task is to find the key having the maximum value.

Examples :

Input : {'Audi':100, 'BMW':1292, 'Jaguar': 210000, 'Hyundai' : 88}
Output : Jaguar

Input:  {'Geeks':1900, 'for':1292, 'geek' : 88}
Output:  Geeks

 

Method #1: Using max() function




# Python code to find key with Maximum value in Dictionary
   
# Dictionary Initialization
Tv = {'BreakingBad':100, 'GameOfThrones':1292, 'TMKUC' : 88}
  
Keymax = max(Tv, key=Tv.get)
print(Keymax)


Output:



GameOfThrones

 

Method 2: Using max() with lamda function




# Python code to find key with Maximum value in Dictionary
   
# Dictionary Initialization
Tv = {'BreakingBad':100, 'GameOfThrones':1292, 'TMKUC' : 88}
  
Keymax = max(Tv, key= lambda x: Tv[x])
print(Keymax)


Output:

GameOfThrones

 
Method 3: Using operator




# Python code to find key with 
# Maximum value in Dictionary
import operator
  
# Dictionary Initialization
Car = {'Audi':100, 'BMW':1292, 'Jaguar': 210000, 'Hyundai' : 88}
  
# Getting max item
keyMax = max(Car.items(), key = operator.itemgetter(1))[0]
print(keyMax)


Output:

Jaguar

 
Method 4:




# Python code to find key with Maximum value in Dictionary
  
# Dictionary Initialization
Company = {'GFG':10000, 'Hashd':2292, 'Infy': 200}
  
# taking list of car values in v
v = list(Company.values())
  
# taking list of car keys in v
k = list(Company.keys())
  
print(k[v.index(max(v))])


Output:

GFG
