Python program to find the second maximum value in Dictionary
In this article, we will learn about the solution to the problem statement given below.
Problem statement − We are given two integers, we need to print the second maximum value in the dictionary
Now let’s observe the concept in the implementation below−
Approach 1 − Using sorted() function by negative indexes
Example
#input
example_dict ={"tutor":3, "tutorials":15,
"point":9,"tutorialspoint":19}
# sorting the given list and get the second last element
print(list(sorted(example_dict.values()))[-2])
Output
15
Approach 2 − Here we use sort method on the list and then access the second largest element
Example
list1 = [11,22,1,2,5,67,21,32]
# using built-in sort method
list1.sort()
# second last element
print("Second largest element in the list is:", list1[-2])
Output
Second largest element in the list is: 32
Approach 3 − Here we apply the brute-force method without using a built-in function
Example
list1 = [11,22,1,2,5,67,21,32]
#assuming max_ is equal to maximum of element at 0th and 1st index
and secondmax is the minimum among them
max_=max(list1[0],list1[1])
secondmax=min(list1[0],list1[1])
for i in range(2,len(list1)):
# if found element is greater than max_
if list1[i]>max_:
secondmax=max_
max_=list1[i]
#if found element is greator than secondmax
else:
if list1[i]>secondmax:
secondmax=list1[i]
print("Second highest number is the list is : ",str(secondmax))
Output
Second highest number is the list is : 32
Conclusion
In this article, we have learned about how we can find the second maximum value in a dictionary ).
