How to convert boto3 code to Go
- Add your codePaste it into the Python (boto3) editor, drag in a file, or keep the sample to see how it works.
- Convert to GoClick the button or press Ctrl + Enter. The result streams into the right-hand editor.
- Review and use itCopy or download the result, then test it before you rely on it. AI output is a strong first draft, not a guarantee.
How boto3 maps to the AWS SDK for Go v2
The Go SDK starts from a shared configuration: cfg, err := config.LoadDefaultConfig(ctx) reads credentials and region the same way boto3 does, from environment variables, ~/.aws profiles or an IAM role. Each service then gets a client with s3.NewFromConfig(cfg). See configuring the Go SDK for the options.
Calls take a context.Context and an input struct, and return an output plus an error: out, err := client.ListObjectsV2(ctx, &s3.ListObjectsV2Input{Bucket: aws.String(bucket)}). Optional fields are pointers, so string and number values are wrapped with helpers like aws.String and aws.Int32. boto3 paginators become Go paginators such as s3.NewListObjectsV2Paginator with a HasMorePages loop.
Python exceptions become returned errors. To check for a specific AWS error, the Go SDK uses errors.As with typed errors from each service's types package, or the generic smithy.APIError interface for the error code. The AWS SDK for Go v2 developer guide has examples for each service.
Tips for better results
- Run
go mod tidy. The output importsgithub.com/aws/aws-sdk-go-v2/configand one module per service. Tidy fetches them all. - Check pointer handling. Reading output fields often means dereferencing pointers. Use
aws.ToStringand similar helpers so nil values don't panic. - Use the DynamoDB attributevalue package. For typed items,
feature/dynamodb/attributevaluemarshals Go structs, which is cleaner than buildingAttributeValuemaps by hand. - Pass context through. Keep the
ctxparameter in your functions so callers can set timeouts and cancel long-running calls. - Handle every error. Replace any ignored errors (
_) in the output with real handling before you rely on the code.
Frequently asked questions
Does the output use AWS SDK for Go v1 or v2?
v2. It uses config.LoadDefaultConfig, per-service modules and context-aware calls. v2 is the version AWS recommends for Go.
How do boto3 resources convert to Go?
Go has no resource interface, so resource calls become the underlying client operations. For example, Table.get_item becomes dynamodb.GetItem with an attribute-value key.
Can I run the result in AWS Lambda?
Yes. Wrap the logic in a handler, start it with github.com/aws/aws-lambda-go/lambda, and deploy it on the provided.al2023 runtime as a compiled binary.
