How to add new keys to an already created python dictionary

Question

I am learning Python. I want to know how to add new keys to an already existing dictionary. If there are multiple keys to add then can I add them all at once or one by one?

Answer 1

my_dict = {'name':'Jack', 'age': 26}

my_dict['address'] = 'Downtown'  

# Output: {'address': 'Downtown', 'name': 'Jack', 'age':26}
print(my_dict)

And if you want to add multiple keys refer to the following example

x={1:2}
print(x)
d={3:4,5:6,7:8}
x.update(d)
print(x)

#output will be {1:2,3:4,5:6,7:8}
