Create a resource service client by name. different CA cert bundle than the one used by botocore. An adverb which means "doing without understanding". A consequence here is that in a Lambda function, if youre only making API calls from the handler function itself, theres not much need for the session, but if you start to modularize your code into separate Python functions and classes, they should take sessions as input, and thus you should be creating a session in your handler in your function initialization code, not per invocation (also in your initialization, create sessions for any assumed roles you use but see below for how to make that work properly). user_agent_extra is specified in the client config, it overrides uses. Valid values are: Uses the STS endpoint that corresponds to the configured region.

This is how you can use the shared credentials file to store and reuse the credentials in the SDKs such as boto3. My argument is that when youre writing application or library code (as opposed to short, one-off scripts), you should always use a session directly, rather than using the module level functions. Notify me via e-mail if anyone answers my comment. See the https://pritul95.github.io/blogs/boto3/2020/08/01/refreshable-boto3-session/. [1]: The reason is, with the config file, the CLI or the SDK will automatically look for credentials in the ~/.aws folder.
