How to pass a variable to remove hook?

I finally found a solution to this that doesn’t require manual interfaces thanks to @jdstrand!

In my bash install hook (running as root):

#!/bin/bash
mkdir -m 3777 $SNAP_COMMON/users

In my bash remove hook (running as root):

#!/bin/bash
find $SNAP_COMMON/users -maxdepth 1 -mindepth 1|while read filepath; do
    if [[ $filepath == *.appvar ]];
    then
        while IFS= read -r datastring
        do
            echo "$datastring"
        done < "$filepath"
    fi
done

And in my python code (running as the user):

import subprocess
subprocess.call('umask 027', shell=True)
subprocess.call('echo "' + my_variable.strip() + '" > $SNAP_COMMON/users/$(id -u).appvar', shell=True)
