Initialize an Empty Dictionary in Python (original) (raw)
Last Updated : 12 Apr, 2025
To initialize an empty dictionary in Python, we need to create a data structure that allows us to store key-value pairs. Different ways to create an Empty Dictionary are:
- Use of { } symbol
- Use of dict() built-in function
- Initialize a dictionary
Use of{ }symbol
We can create an empty dictionary object by giving no elements in curly brackets in the assignment statement.
Python `
d = {}
print(d) print("Length:", len(d)) print(type(d))
`
Output
{} Length: 0 <class 'dict'>
Use of dict() built-in function
Empty dictionary is also created by dict() built-in function without any arguments.
Python `
d = dict()
print(d) print("Length:",len(d)) print(type(d))
`
Output
{} Length: 0 <class 'dict'>
Initialize a dictionary
This code demonstrates how to create an empty dictionary using a dictionary comprehension. It initializes d with no elements and then prints the dictionary, its length, and its type.
Python `
d = {key: value for key, value in []}
print(d) print("Length:", len(d)) print(type(d))
`
Output
{} Length: 0 <class 'dict'>
