EbookLib is a Python library for managing EPUB2/EPUB3 files. It’s capable of reading and writing EPUB files programmatically.
You can read more about this python library on this website.
First, I install with the pip tool:
C:\Python310>python -m pip install --upgrade pip

I used a the simple python script from the last tutorial to test it:
The last tutorial used the default script from the official webpage.
Compared to the default script, I made changes, the selection in the Romanian language and diacritics...
from ebooklib import epub

book = epub.EpubBook()

# set metadata
book.set_identifier('__1976')
book.set_title('')
book.set_language('en')

book.add_author('Autho: Cătălin George Feștilă')

# create chapter
cap001 = epub.EpubHtml(title='Intro', file_name='capitolul_01.xhtml', lang='ro')
cap001.content=u'<h1>Introducere</h1><p>Această carte este...</p>'

# add chapter
book.add_item(cap001)

# define Table Of Contents
book.toc = (epub.Link('capitolul_01.xhtml', 'Introducere', 'introducere'),
             (epub.Section('O carte simplă'),
             (cap001, ))
            )

# add default NCX and Nav file
book.add_item(epub.EpubNcx())
book.add_item(epub.EpubNav())

# define CSS style
style = 'BODY {color: white;}'
nav_css = epub.EpubItem(uid="style_nav", file_name="style/nav.css", media_type="text/css", content=style)

# add CSS file
book.add_item(nav_css)

# basic spine
book.spine = ['nav', cap001]

# write to the file
epub.write_epub('ro_lan_test.epub', book, {})
This is the result of the epub file:
