Python program to find the second maximum value in Dictionary

PythonServer Side ProgrammingProgramming

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

 Live Demo

#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

 Live Demo

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

 Live Demo

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 ).
