In Python, you can create an empty dictionary by using curly braces {} or by using the built-in dict() function without any arguments. Here’s how you can do it:
Using curly braces:
empty_dict = {}
Using the dict() function:
empty_dict = dict()
Both of these approaches 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'] = 42
Or, you can initialize a dictionary with some initial values:
initial_dict = {'name': 'John', 'age': 30, 'city': 'New York'}
Note: dictionaries in Python are mutable, and you can add, modify, or remove key-value pairs freely.
Python creates an empty dictionary example
Here’s an example of creating an empty dictionary and then adding some key-value pairs to it:
# Create an empty dictionary
empty_dict = {}
print(empty_dict)
# Adding key-value pairs to the dictionary
empty_dict['name'] = 'Alice'
empty_dict['age'] = 25
empty_dict['city'] = 'London'
# Printing the dictionary
print(empty_dict)
Output:
In this example, we first create an empty dictionary named empty_dict using curly braces {}. Then, we add three key-value pairs to the dictionary: ‘name’: ‘Alice’, ‘age’: 25, and ‘city’: ‘London’. Finally, we print the dictionary to see the result. As you can see, the dictionary contains the added key-value pairs.
