Creating a Basic Serverless Function
Let’s start by building a function that checks if a given number is even.Import the Runpod library
Create a new python file calledis_even.py
.
Import the Runpod library:
is_even.py
Define your function
Create a function that takes ajob
argument:
is_even.py
- Extracts the input from the
job
dictionary - Checks if the input is an integer
- Returns an error message if it’s not an integer
- Determines if the number is even and returns the result
Start the Serverless function
Wrap your function withrunpod.serverless.start()
:
is_even.py
Complete code example
Here’s the full code for our serverless function:is_even.py
Testing your Serverless Function
To test your function locally, use the following command:- The serverless worker started successfully
- It received the test input
- The function processed the input and returned
True
(as 2 is even) - The job completed successfully
Conclusion
You’ve now created a basic serverless function using Runpod’s Python SDK. This approach allows for efficient, scalable deployment of functions without the need to manage infrastructure. To further explore Runpod’s serverless capabilities, consider:- Creating more complex functions
- Implementing error handling and input validation
- Exploring Runpod’s documentation for advanced features and best practices
