Python Program to Sort a Dictionary by Value

In this example, you will learn to sort a Python dictionary by value.

To understand this example, you should have the knowledge of the following Python programming topics:


Example 1: Sort the dictionary based on values

dt = {5:4, 1:6, 6:3}

sorted_dt = {key: value for key, value in sorted(dt.items(), key=lambda item: item[1])}

print(sorted_dt)

Output

{6: 3, 5: 4, 1: 6}
  • Here, key=lambda item: item[1] returns the values of each key:value pair.
  • From each key:value pair of dt.item(), sorted() sorts the items based on values.

Learn more about sorted() and its parameter key at Python sorted().


Example 2: Sort only the values

dt = {5:4, 1:6, 6:3}

sorted_dt_value = sorted(dt.values())
print(sorted_dt_value)

Output

[3, 4, 6]

In this example, sorted() is used for sorted values only. The values are fed into sorted() using dt.values().
