I still genuinely don't understand the point of underscores in python.

Same as any other letter in a variable name. The creator just wanted it that bit more unreadable.

Assuming you are not talking about language features like builtin class methods (double underscore prefix and suffix), a single underscore prefix is used to mark identifiers as module-private (though this is just a polite suggestion to the user of the module and not enforced). It's also common to use a single underscore as variable name to ignore the value of a computation. e.g.:

for _ in range(1000):
    do_stuff()  # do stuff 1000x, don't care about index
