How do I update a dictionary in Python?

How do I update a dictionary in Python?

You can update a dictionary in Python using the update() method or by assigning a new value to a key.

Can you show me an example using the update method?

Sure! Here's an example:

my_dict = {'a': 1, 'b': 2}
my_dict.update({'b': 3, 'c': 4})
print(my_dict)  # Output: {'a': 1, 'b': 3, 'c': 4}

What if I want to add a new key-value pair?

You can simply assign a value to a new key like this:

my_dict['d'] = 5
print(my_dict)  # Output: {'a': 1, 'b': 3, 'c': 4, 'd': 5}

Is there a way to update multiple keys at once?

Yes, you can use the update() method to update multiple keys at once, just like in the previous example!
