Getting Started With RunPod'S Serverless Python SDK
RunPod’s serverless library enables you to create and deploy scalable functions without managing infrastructure. This tutorial will walk you through creating a simple serverless function that determines whether a number is even.
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 called is_even.py
.
Import the RunPod library:
Define your function
Create a function that takes a job
argument:
This function:
- 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 with runpod.serverless.start()
:
This line initializes the serverless function with your specified handler.
Complete code example
Here’s the full code for our serverless function:
Testing your Serverless Function
To test your function locally, use the following command:
When you run the test, you’ll see output similar to this:
This output indicates that:
- 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
