A Simple Guide to Iterate Through Dictionary in Python – Python Tutorial

In this tutorial, we will write some example codes to introduce how to iterate throng a python dictionary.

Create a dictionary

website = {
    "url": "https://www.tutorialexample.com",
    "name": "Tutorial Example",
    "article_num": 45,
    "is_available": True
}

The result is:

{'url': 'https://www.tutorialexample.com', 'is_available': True, 'article_num': 45, 'name': 'Tutorial Example'}

From the result, we will find the item order of create and print is different.

Iterate through keys

for key in website:
    print("{}: {}".format(key, website[key]))

The output is:

url: https://www.tutorialexample.com
is_available: True
article_num: 45
name: Tutorial Example

Iterate through values

for value in website.values():
    print(value)

The output is:

https://www.tutorialexample.com
True
45
Tutorial Example

Iterate though keys and values

for key, value in website.items():
    print("{}: {}".format(key, value))

The output is:

url: https://www.tutorialexample.com
is_available: True
article_num: 45
name: Tutorial Example
