As it is described in the Amazon official documentation link here It is as simple as just creating a zip of all the folder contents after installing the required packages in your folder where you have your python lambda code.

As Vineeth pointed above in his comment, The very first step in moving from an inline code editor to a zip file upload approach is to change your lambda function handler name under configuration settings to include the python script file name that holds the lambda handler.

lambda_handler => {your-python-script-file-name}.lambda_handler.

Other solutions like python-lambda and lambda-uploader help with simplifying the process of uploading and the most importantly LOCAL TESTING. These will save a lot of time in development.

Lambda with Python libraries
If you go with infrastructure as code, you can add the libraries you need as part of the CI/CD pipeline run, zipping the file at that point. This avoids polluting your Git repo with libraries. More on reddit.com

How can I add third party python dependencies to a Lambda function?
You have multiple way to package your Lambda function as shown here https://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html . However I found something much easier, which is basically deploying a simple Cloud9 IDE. Connect to it, load your lambda function. You will get a Linux shell, simply cd to your lambda directory, run pip install, save & deploy and you are good to go. More on reddit.com

Working with layers for Python Lambda functions - AWS Lambda
The packages in your layer must be compatible with Linux. Lambda functions run on Amazon Linux. You can create layers that contain either third-party Python libraries installed with pip (such as requests or pandas) or your own Python modules and packages.

February 4, 2024 -

Utilizing third-party packages is a staple in most Python projects, making the pip installation process indispensable. However, when working with AWS Lambda functions in Python, integrating these packages can present a unique set of challenges. This tutorial delves into a variety of approaches, ranging from downloading wheel files to leveraging Docker. Yet, the focus here is on a remarkably efficient technique: direct pip installation within the Lambda environment itself.
While acknowledging its constraints, this method proves to be highly practical, particularly for straightforward projects or less complex codebases. The tutorial offers a step-by-step guide, demonstrating the convenience and applicability of this approach in real-world scenarios. Dive into the details by watching the accompanying video, where I walk you through each stage of this process.

January 20, 2025 - Currently, you either have to zip up your Lambda function and Linux compatible dependencies, or upload your dependencies as a Lambda Layers. If you’ve played around with Google Cloud Functions and Azure Function before then you would know that it can be as easy as to writing a wish list in the requirements.txt. To add extra complexities, some of the Python packages need to compile C or C++ extensions (packages such as Numpy and Pandas). This could be a bit of a hassle if you want to use your macOS or Windows machine to pip install -t .

r/aws on Reddit: Lambda with Python libraries
January 23, 2023 -

I've deployed Python runtime Lambda functions that require functions outside the standard library a couple of different ways:

  1. Layers. Pros: really simple to attach once they are created. Cons: I don't like having a bunch of layers lying around in my Lambda UI. I don't like maintaining when new versions need to be attached, either. I've not created them using CloudFormation yet, though I see it can be done.

  2. Installing libraries locally in my Git repo with my Lambda handler file, then zipping up the entire folder when committing and deploying. Pros: easy to do, easy to keep the version of the library tightly coupled with the project. Cons: pollutes my Git repo with potentially hundreds of files that I'm not really tracking. Takes longer to deploy the function each time.

  3. Bundling the whole thing up as a Docker image and deploying that way. Pros: really clean to execute. Cons: more overhead with building containers, which I usually do in CodeBuild for reasons. Takes a while to deploy the image each time, and I think slower cold starts if the function hasn't been invoked in a while.

Am I missing any other options? What do you use and why?
