.docx files are much more than text - they are actually a collection of XML files with a very specific format. To read/write them easily, you need the python-docx module. To adapt your code:

from docx import Document

...

elif self.docURL == "" or self.docURL.split(".")[-1] == "docx":
    text = self.textEdit_3.toPlainText()
    doc = Document()
    paragraph = doc.add_paragraph(text)
    doc.save(self.docURL[:-4] + "_EDITED.docx"

and you're all set. There is much more you can do regarding text formatting, inserting images and shapes, creating tables, etc., but this will get you going. I linked to the docs above.
