Random User Creator App

We are going to create an app which will make an API call to http://jsonplaceholder.typicode.com/users and get a list of random users. Then our app will clean up the returned list of users and store them in a .json file.

Steps to follow:

Create an API function:

• Import necessary library for making an API call.
• Make the API call to this URL -> http://jsonplaceholder.typicode.com/users
• Check the status code, return object (res.json())
• Wrap the API function in try/except block.
• Return the return object.

Create a cleanup function:

• Take the return object as parameter and transform the return object. (Before starting with transforming this return object, check its data type as it may not be a dictionary. Plan your code according to its data type)
• Create a new Python dictionary containing all 10 users and their details from the return object. (Items to be included: id, name, username, email)
• Return the Python dictionary

Creata a function to write the users dictionary to a .json file:

• Take a dictionary as the parameter
• Open up a new file (or create if it isn't existing)
• Dump the Python dictionary into this file

Create a main.py file:

• Import all your modules
• Create the main app logic here

Things to remember:

• Use a virtual environment.
• Create separate functions for all the steps.
• Modularize your code (either create a separate file for each function or create a file called utils.py and store all the functions in this file)
• Wrap the necessary parts of your functions in try/except blocks.
• Create a requirements.txt file at the end of your project to store all the dependancy information. (pip freeze > requirements.txt)
