diff of a file in a specific commit and HEAD

How can I compare the difference to HEAD and the last commit that contains specific file?

To find the last commit that contains the file, read the information in git diff file against its last change . However, running the command git diff HEAD 7de795700d64093afcbd79af03ea4fcfc3ec25b2 src/rodain_get_directions/nodes/retrieve_content.py on the terminal does not return anything.
