tutorial: running python scripts in aws lambda
aws lambda is a serverless computing service that allows you to run code without provisioning or managing servers. it supports multiple programming languages, including python, making it an excellent choice for running python scripts in a scalable and cost-effective manner. in this tutorial, we'll guide you through the process of running a python script in aws lambda, along with a code example.
prerequisites:
steps:
1. create a python script:
first, create a python script that you want to run on aws lambda. for demonstration purposes, let's create a simple script that calculates the sum of two numbers.
2. package the script:
you need to package your python script and its dependencies into a .zip file. make sure your script is at the root level of the directory.
3. create an aws lambda function:
now, let's create an aws lambda function using the aws management console or aws cli.
replace your-execution-role-arn with the arn (amazon resource name) of the iam role that grants necessary permissions for your lambda function.
4. test the lambda function:
you can test your lambda function using the aws management console or aws cli.
this command will invoke the lambda function with the specified payload (input data) and store the output in the output.txt file.
5. monitor and debug:
aws lambda provides monitoring and logging capabilities through amazon cloudwatch. you can monitor your lambda function's performance, view logs, and debug any issues.
6. (optional) configure triggers:
you can configure triggers to automatically invoke your lambda function in response to events from various aws services like amazon s3, amazon dynamodb, amazon api gateway, etc.
7. cleanup:
remember to clean up resources to avoid unnecessary costs. you can delete the lambda function using the aws management console or aws cli.
