# Python Program to Sort Python Dictionaries by Key or Value

In this tutorial, we will learn to sort dictionaries by key or value in Python. A dictionary can be sorted based on its keys, where the value and the keys are displayed in increasing order of the keys. There is also another way to sort a dictionary and that is based on the values where the keys and the values are displayed in increasing order of the values.

Let's see the input-output format for sorting the dictionary.

Input: {'x': 23, 'y': 60, 'z': 12}

Output: (z, 12) (x, 23) (y, 60)

## Approach 1: sorting using the keys

We will be sorting the keys and the values in increasing the order of keys. We will be using the `sorted() `method to sort the keys. Pass the variable that will store keys in this method. It will return the keys after sorting them in ascending order.

### Algorithm

Follow the algorithm to understand the approach better.

Step 1- Define a variable to store keys

Step 2- Define keys and their values

Step 3- Sort keys using the sorted() method

Step 4- Print keys in sorted order and their respective values

### Python Program 1

Look at the program to understand the implementation of the above-mentioned approach.

``````key_value={}

key_value = 10
key_value = 8
key_value = 77
key_value = 23
key_value = 9
key_value = 43

print("sorting on the basis of keys")

for i in sorted(key_value) :
print ((i, key_value[i]), end =" ")``````

sorting on the basis of keys
(1, 43) (2, 9) (3, 8) (4, 23) (5, 10) (6, 77)

## Approach 2: sorting using the value

In this, we will sort using the value and display the keys and values in increasing order of the value. We will be using the `items()` method to get the keys and values from the dictionary. To sort the values, we will be using the `sorted()` method. To get keys of a particular value we have used a lambda function.

### Algorithm

Follow the algorithm to understand the approach better.

Step 1- Define a dictionary

Step 2- Define keys and their values

Step 3- Sort values using the sorted() method

Step 4- Print the keys and their respective values

### Python Program 2

Look at the program to understand the implementation of the above-mentioned approach.

``````key_value={}

key_value = 10
key_value = 8
key_value = 77
key_value = 23
key_value = 9
key_value = 43

print("sorting on the basis of values")

print(sorted(key_value.items(), key=lambda keyval: (keyval, keyval)))``````

sorting on the basis of values
[(3, 8), (2, 9), (5, 10), (4, 23), (1, 43), (6, 77)]

## Conclusion

In this tutorial, we have seen how to sort a dictionary using keys and values. We have seen how to use the `sorted()` method to sort the keys or values in ascending order.
