Looking at your code:

py.call('pressbutton.pressme', function() {});

Here, you are missing the args parameter of the call, it should be:

py.call('pressbutton.pressme', [], function(result) {});

(note the addition of [] - an empty argument list - there)

Additionally, if you don't have PyOtherSide 1.1 (e.g. from Nemo Mobile "devel" repositories), you have to strip the leading 'file://' from the Qt.resolvedUrl() result for now (PyOtherSide 1.1 and later will strip it for you automatically, but 1.1 is not yet in the Sailfish OS release repositories, it should be with one of the next updates), if the import path should be relative to the QML file:

addImportPath(Qt.resolvedUrl('.').substr('file://'.length));

If you are just adding an absolute, hardcoded path, you can just use that, without Qt.resolvedUrl():

addImportPath('/usr/share/pressbutton/qml');

That should make your example work.

By the way, the Python function can be rewritten as:

def pressme():
    with open("/home/nemo/Documents/file.txt","a") as f:
        f.write("this is example text")

See this article for how "with" is used there. If you want to write line-wise to that file, use f.write('this is example text\n') or even print with the file= keyword argument, like:

def pressme():
    with open("/home/nemo/Documents/file.txt","a") as f:
        print("this is example text", file=f)

Let me know if that works for you and if you have any other questions :)
