# How to get minimum value keys from a dictionary in Python

Gutha Vamsi Krishna

In this shot, we will learn how to get the keys with the minimum value in a dictionary.

We will start by defining the problem statement followed by an example.

### Problem statement

Given a dictionary, find all the keys that have minimal value in the dictionary.

### Example

We are given a dictionary that has students’ names as the key and their ages as the value.

### Input

{"john":12,"steve":20,"robert":19, "diana":15,"riya":12}


### Output

[john,riya]


### Explanation

Only john and riya are age 12, which is the minimum value in the given dictionary.

### Implementation

To solve this problem, we will:

• Get all values from a dictionary.
• Find out the minimum value from them.
• Traverse through the dictionary using the for-in loop and list comprehension.
• Check if the present key value equals the minimum value. If it does, we add it to the list.
• Finally, print the list.
#declare dictionary students
students = {
"john":12,"steve":20,"robert":19, "diana":15,"riya":12
}

#find minimum value in dictionary
minimum_value = min(students.values())

#get keys with minimal value using list comprehension
minimum_keys = [key for key in students if students[key]==minimum_value]

#print the minimum keys
print(minimum_keys)

Getting the keys with minimum value

### Explanation

In the code snippet above:

• Line 2: We declare and initialize the dictionary students.
• Line 7: We use the min function and pass all values of the dictionary as a parameter to get the minimum value in the dictionary.
• Line 10: We traverse through the dictionary students and check if the present key’s value is equal to the minimum value. If it is, we use list comprehension to add it to a list.
• Line 13: We print the list of keys that have a minimum value in the dictionary.
