How do I create a dictionary in Python?

How do I create a dictionary in Python?

You can create a dictionary in Python using curly braces. For example: my_dict = {'key1': 'value1', 'key2': 'value2'}.

Can I have a dictionary with different data types?

Yes, dictionaries can hold mixed data types. For instance: my_dict = {'name': 'Alice', 'age': 30, 'is_student': False}.

How do I access a value in the dictionary?

You can access a value by using its key. For example: my_dict['name'] will return 'Alice'.

What if the key doesn't exist?

If the key doesn't exist, it will raise a KeyError. You can use the get() method to avoid this, like my_dict.get('nonexistent_key'), which will return None.
