title: python curl get json tutorial with code example
introduction:
python provides several libraries for making http requests, including the popular requests library. however, you can also use the curl command-line tool to make http requests directly from python scripts. this tutorial will guide you through making a get request to a json api using curl in python, with a step-by-step explanation and code examples.
prerequisites:
step 1: install curl:
if you haven't already installed curl, you can do so depending on your operating system. for linux and macos, curl usually comes pre-installed. for windows, you might need to install it manually by downloading from the official website (https://curl.se/download.html) or using package managers like chocolatey or scoop.
step 2: import subprocess module:
in order to use curl from within a python script, you'll need to import the subprocess module, which allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes.
step 3: make a get request to a json api:
now, let's define a function that sends a get request to a json api using curl. we'll pass the url of the api as an argument to this function.
in the above function:
step 4: usage example:
let's use the get_json function to make a get request to a sample json api (https://jsonplaceholder.typicode.com/....
in this example, if the request is successful, the json response will be printed. otherwise, an error message will be printed.
conclusion:
in this tutorial, you learned how to make a get request to a json api using curl in python. by leveraging the subprocess module, you can interact with command-line tools like curl directly from your python scripts. this method can be useful in situations where using external tools is preferable or necessary.
