Assign values using unique keys

After defining a dictionary we can index through it using a key and assign a value to it to make a key-value pair.

Python3

veg_dict = {}
veg_dict[0] = 'Carrot'
veg_dict[1] = 'Raddish'
veg_dict[2] = 'Brinjal'
veg_dict[3] = 'Potato'
 
print(veg_dict)

Output:

{0: ‘Carrot’, 1: ‘Raddish’, 2: ‘Brinjal’, 3: ‘Potato’}

But what if a key already exists in it?

veg_dict[0] = 'Tomato'
print(veg_dict)

Output:

{0: ‘Tomato’, 1: ‘Raddish’, 2: ‘Brinjal’, 3: ‘Potato’}

We can observe that the value corresponding to key 0 has been updated to ‘Tomato’ from ‘Carrot’.

In this article, we will learn what are the different ways to add values in a dictionary in Python.
