On a scale of 1-10, I think the explanation document deserves a 0 because it really served its purpose well. Great explanation and great video overall (videos actually as there are other parts). Much appreciated!

As someone with a background of a mechanical engineer I especially love your explanation here: kzbin.info/www/bejne/fJTViGB7iMmMY6M It's a solid 10! Virtually everyone else just runs through their calculations in these cases like "something minus something plus an other something divided by two equals this bit here which we're going to use as a float value of this randomly mentioned parameter" :)

Hi, thanks for your video series, very helpful. I have a question... I'm implementing a form (in django) and i don't know how can override the header method passing arguments coming from the form, can you give me a hadn?

Excelente explicación, muchas gracias por ello Como haría si por ejemplo tengo un pdf de 10 páginas, y necesito ponerle como numero de pagina empezando la primera página como número de pagina= 10, la siguiente pagina= 9, y asi llegar a la última página del documento pdf el número de pagina= 1.

[@mustafacan2361]

Hello sir. Thanks for your records. They were totally helpful for pdf operation. Is there any reason that you did not use fd.readlines() /readline() instead of fd.read().decode() ? (file should be opened as "with open(name) as fd:" for readlines()/ readline() method.)

[@MURALIKRISHNAhai]

Thank you Could you please explain how to attach existing pdf files to the newly created pdf and establish the links from the newly created pdf to the other added pdf pages instead of writing content from a text file I am using existing pdf files to attach to the pdf made by your lectures and trying to establish the links from top page to other pages

[@ChartExplorers]

Hi @MURALI KRISHNA, I am actually in working on my next set of videos to describe this. In the mean time this is a great article to get you started realpython.com/creating-modifying-pdf/#using-the-pdffilewriter-class You will have to use the library PyPDF2 library to merge PDFs.

[@spiralcarbon8658]

Thank you Sir. May i ask how to save the output to a specified folder.

[@ChartExplorers]

You're welcome. To save to a specific folder you will pass the folder path and then the pdf name to pdf.output(). for example if I am on Windows and wanted to save my pdf to my desktop and call it my_pdf.pdf I could use the following pdf.output('C:\Users\bvalg\Desktop\my_pdf.pdf')

[@aliuslubas]

Thanks a lot for this video. I would be appreciated for a video contaning more information on this regard. with open(name, 'rb') as fh: txt = fh.read().decode('latin-1')

[@MURALIKRISHNAhai]

With FPDF package instead of depending on text files for writing information into our PDF file can we use the existing PDF files to attach to our PDF file. It's like whatever the pdf file we are creating we will create it with the already existing pdf file

[@ChartExplorers]

Yes you can. I will be putting out a video tomorrow that talks about this problem. The link I sent to you in my other replies talks about how to do this. You will need to use the PyPDF2 library. realpython.com/creating-modifying-pdf/#concatenating-and-merging-pdfs

[@ChartExplorers]

Hi I released this video a little earlier than I planned. kzbin.info/www/bejne/ZnOYf2mOqZp-brM This discusses how to extract text from PDF files using PyPDF2. It doesn't address your specific question, but should give you a head start on solving your problem. You will have to also use PyPDF2 and FPDF2 to accomplish your goal. I will create a specific video on this topic in the coming days.

[@MURALIKRISHNAhai]

Hi Mr. Bradon, Here is what I have::: A bunch of PDF files which has complex equations+ tabular headers and footers+ page index etc... Here is what I tried::: 1.I tried what you did in part1,2,3 &4 of handling pdf with python 2.I have converted all those bunch of pdf files into .txt files {But after conversion they look weirdly bad, But I was hoping I could able to reproduce the same good PDF files with those .txt files} 3.I just followed your lectures from part1 to part4 and use those .txt files to create one single PDF with index of every individual pdf file name and activated links {I have used for loop many places to iterate through all .txt files and add them to the wishful large pdf file} Do you think is this the right way to follow. I am dearly waiting for your new video on how to merge pdf files and create a good looking index file after merging to create one single large pdf file

[@ChartExplorers]

@@MURALIKRISHNAhai If I understand your needs correctly, it sounds like it will be much easier to merge the existing pdf's together will be much easier (because then you can keep the formatting). I'm almost done with the video :)

Hi Mr. Bradon, I am very much excited and looking forward to watch your next video on pdf merging with TOC creation.

Hello, before anything I wanna to thank u for this videos, helped me a lot. I wanna ask u if u know how can I fix some error. I'm saving some form in a database and creating PDFs with this data, but the multi_cell attribute isn't work as I expect, it's not breaking lines. Have u have some idea how can I fix this? Again, thx for this videos and congratulations to your channel.

[@michaelpolicella2588]

Great teacher. somehow though the text that is displayed on chrome has each line spaced to the complete width of the page. Effectively the words have varying space between them. I have Win10 . Tried all sorts of things but nothing worked and could not find a solution on the web. But really , love the tutorial.

i tried using chatgpt to create an article but when i wanted to convert it into pdf using the multi_cell it did not work instead it kept on throwing an error........it said something about decode('latin-1').....please how can i fix this

[@souleymanetraore1353]

Thank you for these videos can u make one on how to concatene pdf files with fpdf please.

[@ChartExplorers]

Hi Souleymane, fpdf is a library for creating pdf's but it cannot modify (merge split) them. In order to merge or split a pdf you would need to use another library... something like pypdf4 github.com/claird/PyPDF4. I would be happy to make a video on this. I have a couple other videos that I've been working on that I will get out before I can get to this video. Do you have a deadline of when you need this information?

[@carlcreighton6157]

I am doing a web scraper project and am trying to move the text I scrape onto a pdf. however the websites that I am scraping have strange symbols that dont translate into txt files unless you substitute the characters for another. and I cannot decode because they are strings. any advice? python will print the code in run box but will not make it a txt.

[@cantstandya3761]

Hi, one thing I don't seem to understand is the footer and header methods; can't see that they are being called; are these overloaded methods and run automatically by the constructor?

[@cantstandya3761]

Great tutorial by the way.

[@cantstandya3761]

Forget it; found the answer in the api-documentation - and for those interested here is the statement from the documentation; "Footer to be implemented in your own inherited class. This is automatically called by add_page() and close() and should not be called directly by the user application. The default implementation performs nothing: you have to override this method in a subclass to implement your own rendering logic."

[@cantstandya3761]

I'm guessing the same applies to header :)

[@rickygevais9412]

This is great I mainly use Java by using Java I mean started to learn Java but after seeing this I going to switch to python because this looks incredible. How did you manage to come up with this idea? It also looks so professional like a pdf book you would buy, what you made pick 20,000 leagues under the sea? I love the way you used page objects, how did you come up with that, did you design first hand before writing the code.

[@ChartExplorers]

Thanks Ricky. I can't take credit for this at all. This is up on the FPDF2 tutorial homepage (pyfpdf.github.io/fpdf2/Tutorial.html) I've made a few tweaks here and there to make it a little easier to understand or to demonstrate certain examples more clearly. What do you build with Java?
