Python program to find the highest 3 values in a dictionary
In this article, we will learn about the solution and approach to solve the given problem statement.
Problem statement
Given a dictionary, we need to find the three highest valued values and display them.
Approach 1 − Using the collections module ( Counter function )
Example
from collections import Counter
# Initial Dictionary
my_dict = {'t': 3, 'u': 4, 't': 6, 'o': 5, 'r': 21}
k = Counter(my_dict)
# Finding 3 highest values
high = k.most_common(3)
print("Dictionary with 3 highest values:")
print("Keys: Values")
for i in high:
print(i[0]," :",i[1]," ")Output
Dictionary with 3 highest values: Keys: Values r : 21 t : 6 o : 5
Approach 2 − Using the heapq module ( nlargest function )
Example
from collections import Counter
# Initial Dictionary
my_dict = {'t': 3, 'u': 4, 't': 6, 'o': 5, 'r': 21}
k = Counter(my_dict)
# Finding 3 highest values
high = k.most_common(3)
print("Dictionary with 3 highest values:")
print("Keys: Values")
for i in high:
print(i[0]," :",i[1]," ")Output
Dictionary with 3 highest values: Keys: Values r : 21 t : 6 o : 5
Conclusion
In this article, we learned about the approach to convert a decimal number to a binary number.
