Step-by-Step Guide to Creating an Empty Dictionary with Examples
In Python, you can create an empty dictionary using either curly braces {}
or the dict()
constructor. Here are examples of both methods:
Using curly braces {}
:
empty_dict = {}
Using the dict()
constructor:
empty_dict = dict()
Both of these methods will create an empty dictionary named empty_dict
. You can then add key-value pairs to this dictionary as needed. For example:
empty_dict['key1'] = 'value1'
empty_dict['key2'] = 'value2'
Now empty_dict
will contain two key-value pairs:
{'key1': 'value1', 'key2': 'value2'}
Creating an empty dictionary is often the starting point when you want to dynamically build a dictionary and populate it with data later in your Python code.
