How do I get the font width metadata property using Fonttools?

I'm looking for a way to retrieve this property for a script I'm writing:

What is the correct way to accomplish this using FontTools?

This is not an issue.

Anyway:

font = TTFont(file)
width = font['OS/2'].usWidthClass

width is an integer (1-9), and you can map them as you prefer. For example: https://learn.microsoft.com/en-us/typography/opentype/spec/os2#uswidthclass

Will this work for both TTF and OTF fonts? Sorry for such a simple question, just trying to get a grasp on this.

Yes, both have OS/2 table
