Text-Replace in docx and save the changed file with python-docx

Question

I'm trying to use the python-docx module to replace a word in a file and save the new file with the caveat that the new file must have exactly the same formatting as the old file, but with the word replaced. How am I supposed to do this?

The docx module has a savedocx that takes 7 inputs:

• document
• coreprops
• appprops
• contenttypes
• websettings
• wordrelationships
• output

How do I keep everything in my original file the same except for the replaced word?

this worked for me:

def docx_replace(old_file,new_file,rep):
    zin = zipfile.ZipFile (old_file, 'r')
    zout = zipfile.ZipFile (new_file, 'w')
    for item in zin.infolist():
        buffer = zin.read(item.filename)
        if (item.filename == 'word/document.xml'):
            res = buffer.decode("utf-8")
            for r in rep:
                res = res.replace(r,rep[r])
            buffer = res.encode("utf-8")
        zout.writestr(item, buffer)
    zout.close()
    zin.close()
