The issue is I need to parse a string line delimited by spaces (but not exactly) into a Pydantic model. The field names are known and types for this task are not important, so keeping str is fine.

I’m unfamiliar with Pydantic, but I assume there is a way to leverage the BaseModel.model_validate method or similar to make the parsing more natively.

For the sake of example I trimmed the log and model!

Example log file:

79a59df900b949e55d DOC-EXAMPLE-BUCKET1 [06/Feb/2019:00:00:38 +0000]

The model:

class S3AccessLogEntry(BaseModel):
    owner: str
    bucket: str
    timestamp: str
