I'm a notetaker for my college, and as part of my duties I have to upload my notes daily. As I type them, this is something I can do from my computer, without needing a scanner. Generally, this involves:
Find the .pdf with the "highest number" (The .pdf's are named
XYis a number. I number them starting at 01 on the first lecture and going up. I want to get the most recent one).
Copying the .pdf to a specific folder (I'll need to rename the .pdf, to something else, so working with a copy makes more sense).
Renaming it in the following format -
SUBJ XYZ MM-DD-YYYY.pdf, where
SUBJis the subject classification (like
MUS, etc), and
XYZis the course number.
Opening a specific webpage, and the GUI file manager so I can "drag and drop" the file correctly (I don't know how to do this in a better way, the webpage has a "select a file" and then "click to upload", I haven't seen any protocol I can upload it without this kind of stuff).
Move the renamed folder into some subfolder of the "specific folder" mentioned before, so "clean things up". Deleting the file would also probably be fine, but this is the implementation I currently have.
There are various improvements I've considered. One is insteading of appending the current date, looking for the most recent date I had that class (which is usually something like
The files are generically stored in the following directory:
In this particular example,
<course name> is
cryptography, and files are named
crypt15.pdf as an example.
I'm wondering if people have generic suggestions for how to clean this up. Some things (like the try/except used) seem like it's pretty obvious I should change, and I just need to sit down and work on it.
