styles['Heading 1'].next_paragraph_style don't work well

[waterdr0p]

https://python-docx.readthedocs.io/en/latest/user/styles-using.html#add-or-delete-a-style
issue: I have tried following python demo code, but I can't see them work well in office word2016.(No Error Raised)

'''

from docx import Document
document = Document()
styles = document.styles

styles['Heading 1'].next_paragraph_style = styles['Body Text']
'''

my demo code

styles = document.styles
styles['Heading 1'].next_paragraph_style = styles['Colorful Grid']
document.add_paragraph("Working with Styles", style='Heading 1')
p7 = document.add_paragraph('next_paragraph_style' * 20)

ipython shell code

In [14]: styles['Heading 2'].next_paragraph_style
Out[14]: _ParagraphStyle('Normal') id: 2512638940664

I believe 'Colorful Grid' is a table style. Does it work with paragraph styles?

[waterdr0p]

I tried using paragraph styles, 'Colorful Grid' is another try for table style, but still don't work.
The code:
import os
from docx import Document
document = Document()
styles = document.styles
styles['Heading 1'].next_paragraph_style = styles['List Bullet']
document.add_paragraph("Working with Styles", style='Heading 1')
p7 = document.add_paragraph('next_paragraph_style' * 20)
fn = 'styles.docx'
document.save(fn)
os.popen(fn)

So it looks like no error is raised. What's the behavior you expect and what behavior are you observing instead?

[waterdr0p]

I expect the next paragraph style will be "List Bullet" by default, but the variable "p7" create paragraph style for "Normal" instead of "List Bullet".
I can also specify paragraph styles through "p7 = document.add_paragraph('next_paragraph_style' * 20, style='List Bullet')" to observe the different with "styles['Heading 1'].next_paragraph_style = styles['List Bullet']".

This setting isn't operative in python-docx, only in Word. If you want to add a following paragraph in python-docx, you'll need to set it to the style you want yourself.

OK, I see, thank you.
