Session - Boto3 1.34.74 documentation

You can configure each session with specific credentials, AWS Region information, or profiles. The most common configurations you might use are:

Note

Only set the profile_name parameter when a specific profile is required for your session. To use the default profile, don’t set the profile_name parameter at all. If the profile_name parameter isn’t set and there is no default profile, an empty config dictionary will be used.

For a detailed list of per-session configurations, see the Session core reference.
