Removing personal information from the comments in a word file using python

I want to remove all the personal information from the comments inside a word file.

Removing the Authors name is fine, I did that using the following,

document = Document('sampleFile.docx')
core_properties = document.core_properties
core_properties.author = ""
document.save('new-filename.docx')

But this is not what I need, I want to remove the name of any person who commented inside that word file.

The way we do it manually is by going into Preferences->security->remove personal information from this file on save
