How to Print a Dictionary in Python
Last Updated : 27 Sep, 2024
Python Dictionaries are the form of data structures that allow us to store and retrieve the key-value pairs properly. While working with dictionaries, it is important to print the contents of the dictionary for analysis or debugging.
Example: Using print Function
Python # input dictionary input_dict = { 'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': [ 'Python', 'Java'] } # printing dict using print function print(input_dict) Output{'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Python', 'Java']} Explanation: In this example, the below code defines a dictionary named `input_dict` with key-value pairs and a list as a value and then prints the dictionary using the `print` function.
We will explore all the possible ways with practical implementation to Print a Dictionary in Python.
Print a Dictionary in Python Using For Loop
In this approach, we are using a for loop to iterate over the key-value pairs of the input_dict, and we are printing each pair in the key: value format. Using the print statement, each of the dictionary pairs is properly printed.
Python # input dictionary input_dict = { 'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java'] } # printing using For Loop for key, value in input_dict.items(): print(f"{key}: {value}") Outputname: GeeksforGeeks website: www.geeksforgeeks.org topics: ['Algorithms', 'Data Structures', 'Python', 'Java']
Print a Dictionary in Python Using pprint Module
In this approach, we are importing the pprint module and using it to print the contents of the input_dict without using any looping. Using this module, we print the dicoanory in a more readable format as each of the key: value pair is printed in separate lines.
Python import pprint # input dictionary input_dict = { 'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java'] } # printing using pprint module pprint.pprint(input_dict) Output{'name': 'GeeksforGeeks', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java'], 'website': 'www.geeksforgeeks.org'} Print a Dictionary in Python Using f-String
In this approach, we are printing the dictionary using F- string in Python.The formatted string f"{input_dict}" is used to print the entire dictionary in a more readable way. The {input_dict} part of the string is replaced with the actual contents of the dictionary when it is printed.
Python # input dictionary input_dict = { 'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java'] } # printing dict using Formatted String print(f"{input_dict}") Output{'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java']} Print a Dictionary in Python Using List Comprehension
In this approach, we are using list comprehension to iterate over the key-value pairs of input_dict, and we are printing each pair in key:value format on a separate line. This is similar to For Loop but it is more modern than the traditional one.
Python # input dictionary input_dict = { 'name': 'GeeksforGeeks', 'website': 'www.geeksforgeeks.org', 'topics': ['Algorithms', 'Data Structures', 'Python', 'Java'] } # printing dict using list comprehension [print(f"{key}: {value}") for key, value in input_dict.items()] Outputname: GeeksforGeeks website: www.geeksforgeeks.org topics: ['Algorithms', 'Data Structures', 'Python', 'Java']
Conclusion
In conclusion, printing dictionaries in Python is an important task for analyzing and debugging code. This article explored various methods, including using the print function, for loop, pprint module, formatted string, and list comprehension, providing a proper methods for developers to choose the most suitable approach based on their specific needs and preferences.
