Python Requests — get(), json()

Python requests are used to fetch content from web pages, which are identified by URLs (Uniform Resource Locators). When you make a get() request to a specific URL, it returns a response object containing the data from the webpage. The json() method converts this response data from JSON format into a Python data structure, typically a dictionary.

Exhibit 25.52 provides an example of the use of a Python request to retrieve data. The code uses the get() function to pull JSON data on the charmeleon pokemon from the pokemon api.

Pokemon: Extracting for Pokemon data with Pokemon API

# import requests module
import requests

# Making a get request for data on the charmeleon pokemon
response = requests.get('https://pokeapi.co/api/v2/pokemon/charmeleon')

# Convert pokemon.co JSON data to dictionary type and store in pk_charmeleon_data
pk_charmeleon_data = response.json()

# Print keys to reveal what information is contained in the data
print(pk_charmeleon_data.keys())  

# Print json data using loop
k = 1
for key in pk_charmeleon_data:
    print('\n' + key, ":", pk_charmeleon_data[key])
    if k == 3:  # limit to the first 3 keys
        break
    k += 1  # Increment k by 1
