Reading the File size for each blob inside a directory of a Blob Container using Azure-Storage-Blob Python

We have an "Azure Blob Storage" for large amounts of data in a cloud. And we have blob containers which contain several directories , and within each directory, we have several blob files of type "Block Blob" and they are '.orc' files. We need to list content of such a directory using the path of the blobs , and then get specific blob information,most importantly the file size for each blob. Currently, we are planning to use this "azure-storage-python" repository for it but are currently lost in its documentation , and are confused on how to achieve our target.

Any help would be highly appreciated. Eagerly waiting for a response!
With Best Regards,
