How can I get the "Date Created" attribute from a file using the python SDK?

The Dropbox API/SDK doesn't return file creation dates (only modified dates), but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.

The "Date created", "Date taken", and "Date uploaded" values you're referring to are from metadata embedded in image, such as using Exif. Some but not all image files contain embedded image metadata like that. The Dropbox API automatically exposes some of this information, such as dimensions and time_taken, where available, via the /2/files/get_metadata endpoint, which is files_get_metadata in the Python SDK. This unfortunately doesn't include the full EXIF data though. You can find all of the metadata offered in the documentation, by expanding the relevant fields, such as by clicking on FileMetadata, MediaMetadata, PhotoMetadata and VideoMetadata. To retrieve any other embedded image metadata not offered there, you'd need to download the image file and extract the image metadata in your code to access those fields.
