I know this module is not very popular but if you know the answer then please help me out with it.
My code is:
from pptx import Presentation
prs = Presentation('template.pptx')
title_slide_layout = prs.slide_layout[0]
# print(len(prs.slide_layout))
slide = prs.slides.add_slide(title_slide_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]
title.text = "Python 3.6 - Turtle Race"
subtitle.text = "Data Analytics&Visualization with random generated data"
prs.save("out.pptx")
An error I have got:
Traceback (most recent call last):
File "D:/!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!_!Piton/turtleRace/presentationMaker.py", line 8, in <module>

So why I have got this error?
It is an issue about the type when you save the file as Strict Open XML Presentation. Try the standard Presentation document.
You can get more informations about relations inside the file using opc-diag:
You can resolve error Here
Trying to fix a old file:
Extract
unzip <FILE> -d old-file
Repackage it into a new fresh file
opc repackage bad-file new-file.docx
diff of relationships
opc diff-item test.docx test-ok.docx .rels
I have found the solution!!!
Before I saved the file(called template) as Strict Open XML Presentation(.pptx)
and not as PowerPoint Presentation(.pptx)
It's now opening the file but now I have another error:
Traceback (most recent call last):
File "D:/!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!_!Piton/turtleRace/presentationMaker.py", line 9, in <module>
title_slide_layout = prs.slide_layout[0]
AttributeError: 'Presentation' object has no attribute 'slide_layout'
Everything is the same just the saving method in PowerPoint has changed.

I am trying to download and extract some data in .tgz file which I need to proceed with my book.
But unfortunately the code does not work.
I am receiving this error:
Traceback (most recent call last):
File "C:...\Python39_SciKit_&_TF_chapter2\main.py",
line 67, in <module>
fetch_housing_data()
File "C:...\Python39_SciKit_&_TF_chapter2\main.py",
line 54, in fetch_housing_data
with tarfile(FILE) as tar_data:
TypeError: 'module' object is not callable
And the code is:
# fetching data
URL = 'https://raw.githubusercontent.com/ageron/handson-ml2/master/datasets/housing/housing.tgz'
FILE = 'housing.tgz'
FOLDER = 'datasets'
def fetch_housing_data():
if not os.path.isfile(FILE):
print(f'Downloading {URL} and saving as {FILE}...')
urllib.request.urlretrieve(URL, FILE)
print('Unpacking file...')
with tarfile(FILE) as tar_data:
tar_data.extractall(FOLDER)
print('Tgz data has been extracted')
else:
print('The file is already in the folder')
And I don't know why this line gives an error:`
with tarfile(FILE) as tar_data:
tar_data.extractall(FOLDER)
Since I was using very similar approach with zip files and it worked.
Why python recognizes this as not collable and how do I make it work?
Problem:
I'm trying to duplicate a slide from a presentation to another presentation, but it returns error:

Copying slides isn't officially supported by the library. There's a lot of discussion about this topic. Look at this github issue for workarounds.
I have a HTML document that uses CSS files and a around a dozen PNG files generated out of matplotlib. To convert this HTML document into a PDF, I installed wkhtmltopdf, on a AWS EC2 Linux instance, in a manner described here.
On the command line, this works
wkhtmltopdf http://www.google.com output.pdf
However, the following Python snippet does not work.
reportCss = pathlib.Path(os.path.join(cssDir, 'report.css'))
w3Css = pathlib.Path(os.path.join(cssDir, 'w3.css'))
#
options = {
'page-size': 'A4',
'dpi': 720,
'margin-bottom': 5
}
css = [str(reportCss), str(w3Css)]
pdfkit.from_file(htmlFilePath, pdfFilePath, options=options, css=css)
I get this error:
QPainter::begin(): Returned false

Can you please advise what am I missing?
Turned out that the PDF folder wasn't existing. The error message is mid leading.
Here is the python reddit program, the code is 100% fine. It's from a tutorial website.

It maybe has something to do with installing python 3.5 any help would be amazing.
You appear to be missing a config file for this module. Check out the documentation:
https://praw.readthedocs.io/en/latest/getting_started/configuration/prawini.html
According to the documentation, you need a praw.ini file, containing a section like this:
[bot1]
client_id=Y4PJOclpDQy3xZ
client_secret=UkGLTe6oqsMk5nHCJTHLrwgvHpr
password=pni9ubeht4wd50gk
username=fakebot1

So on my game I'm making, I'm trying to load the data files needed for the game, and when I load the file with pickle (The file has been loaded, I've double-checked that.) I get this error:
Traceback (most recent call last):

I saw a question like this on Stack Overflow, but it's a little different than my situation, so sorry if this is a duplicate, I'm just trying to figure it out.
You can find my code here. The main script is Deeper.py, just to save time.
If you notice in your repo, you have a Deeper.pyc and Deeper.py. If I run Deeper.py, it raises the same exception as yours. If I run Deeper.pyc, it raises another exception:
Traceback (most recent call last):
File "Deeper.py", line 7, in <module>
ToolbarTile = pygame.image.load("ToolbarTile.png")
pygame.error: Couldn't open Toolbar Tile.png
So, the code (bytecode, some previous version) references ToolbarTile.png, but the exception is about Toolbar Tile.png (with a space). So I changed the file name to account for that.
Now it raises:
Traceback (most recent call last):
File "Deeper.py", line 766, in <module>
else:
File "Deeper.py", line 394, in __init__
def displayCraft(self):
pygame.error: Couldn't open options.png
There's an Options.png in your files, but it looks for options.png (lower case) (even your new code in Deeper.py looks for that). So I changed that.
Now it works, albeit with Deeper.pyc so that must be why you thought:
(The file has been loaded, I've double-checked that.)
Maybe delete the Deeper.pyc and do a git-bisect to see when the bug was introduced (ps: check your toolbar.dat, does it seem okay to you? Also check the way you're using pickle.load. Maybe you should use rb instead of r?)
