Lambda function directory structure implementation
Hey, community! I am new in AWS and I am trying to implement a lambda function with its dependencies. I am stuck. Please, guide me how to create the directory structure correctly and upload .zip to AWS portal, deploy and see the lambda function working. Here are my files. In lambda_function.py spelling_correction is used, in which wiki_fa_80k.vocab is used. Guide me to structure them including dependencies that they use.

Hello.
I think it is a good idea to upload files that can be installed with pip, such as "boto3", as a layer as described in the document below.
https://docs.aws.amazon.com/lambda/latest/dg/packaging-layers.html
https://docs.aws.amazon.com/lambda/latest/dg/creating-deleting-layers.html
Other classes such as "spelling_correction" are probably unique classes created in Python, so I think you can use them for now by uploading them together with "lambda_function.py" in a zip file.
https://docs.aws.amazon.com/lambda/latest/dg/python-package.html
Once you get used to operating AWS, I recommend using IaC such as AWS SAM.

I have created 2 layers for symspellpy and boto3 libraries separately, but I still get this error
"errorMessage": "Unable to import module 'lambda_function': No module named 'symspellpy'",
Can you help me to figure out, please?
For creating layers using Docker containers, please refer to the answer at the following URL. https://repost.aws/questions/QUmvP42wYQRiyOJmvDI5MVtA/error-while-running-python-code-in-aws-lambda-function#ANQ8ctoPV9Q72nMUr5mh8ulg
Also, if you are using the Lambda Python runtime, I don't think you need to create a layer since boto3 is installed. https://docs.aws.amazon.com/lambda/latest/dg/lambda-python.html
Thanks a lot for great information sources! The problem was python3.11 version incompatibility with symspellpy library. Now it works.
