Tutorial bug - "Header" style already exists

[skrupenin1]

I get an error when following the 2.6.3 Adding “zoned” header content section of the latest (0.8.9) tutorial with the 0.8.10 release. The error is "ValueError: document already contains style 'Header'". Steps to reproduce:

from docx import Document
from docx.enum.style import WD_STYLE_TYPE
document = Document()
styles = document.styles
style = styles.add_style("Header", WD_STYLE_TYPE.PARAGRAPH)

Apparently, the default docx template now contains a header style, where it did not previously.

Ah yes! Thanks for reporting this. I wrote the user docs before developing the feature (very far) and by the end of development I figured it wouldn't do for folks to have to add that every time so I ended up adding the Header and Footer styles to the default template.

I'll get this part of the documentation fixed up to be part of the next release. Thanks again for reporting it :)

Fixed in release v0.8.11 on May 15, 2021.
