I've been working with python for a while, and understand how to use tabs correctly, but recently in a project I have started working across Jupyter notebooks and Sublime. When I copy and paste code over, the indentation gets completely messed up. Usually it goes from tabs to 4 spaces and it doesn't like that so I have to manually change every line. It happens on occasion when I copy from one python file to another in just Sublime as well.

Is there some sort of general way, or just setting within those applications, that can prevent this?

Jupyter Notebooks indent with 4 spaces by default. Not sure where you'd be getting tabs unless you originally copy-pasted tabs.

If you want to keep the tabs in SublimeText, select a Python file, go to "Preferences" --> "Settings - Syntax Specific" and add the line:

"translate_tabs_to_spaces": false

Although, if your sources were already mixed (some cells in jupyter use tabs, some use spaces) then it's better to standardise on paste in sublime, and use:

"translate_tabs_to_spaces": true

Also, when you're pasting in SublimeText, instead of just Paste with Ctrl+V, use Paste & Indent: Ctrl+Shift+V

Btw, Python3 recommends 4 spaces by default, almost as a standard. So maybe set that in your editor. Most of them have settings for "Tabs & Indents" somewhere with code formatting.
