Building a Patient Dictionary with User Input in Python

Creating a dictionary to store patient information that can be serialized into a JSON file is an essential skill in Python programming. Here's how you can accomplish this using user inputs, loops, and simple parsing methods. In this guide, we will break down the steps to set up the program, gather input, and save it in the desired format, making it easier for you to follow along.

Understanding the Problem

As you make progress in programming, you might encounter situations where you need to collect multiple pieces of data from users. In this case, we want to gather:

First name

Last name

Age

Gender

We need to ensure the data is stored in a structured way, allowing for easy access and manipulation. Here’s how we can achieve this using a Python script!

Step 1: Setting Up the Dictionary

Firstly, we need to define our dictionary structure. We will create a dictionary called patients that contains a list of patient entries. Each patient entry will itself be a dictionary with keys for first_name, last_name, age, and gender.

Step 2: Gathering User Input

Next, we will set up a loop to continuously ask the user for input until they decide to stop. We'll prompt the user to enter their information in a specific format:

"first name, last name, age, gender"

The following code snippet demonstrates how to implement this loop:

Note: Make sure to advise the users to follow the format strictly, as the program expects exactly four values.

Step 3: Creating Patient Entries

After getting the user input, we need to parse the information and create an entry for each patient. Here’s how you can do this:

Error Handling

Consider incorporating input validation to safeguard against incorrect data entry:

Check if the user input entry has four values.

Ensure that the age value is indeed a number.

Step 4: Saving to JSON File

Once all the necessary data has been collected, we will serialize our patients dictionary into a JSON file. Here’s how you can write the dictionary to a JSON file:

Final Code

Combining all of the steps above, here’s the complete program:

Conclusion

Now you have a simple yet effective way to gather patient information in Python, structure it in a dictionary, and save it into a JSON format. This method can be adapted and expanded for more complex data handling needs as your programming skills grow. Happy coding!
