I recently became the maintainter of PyPDF2 - a library which is pretty old and still has some code that deals with Python versions before 2.4. While I want to drop support for 3.5 and older soon, I see some parts where I'm uncertain why they were written as they are.
One example is this:

The first version is just the pre-2.4 way to use
staticmethod. The two versions aren't quite equivalent, but the difference is so tiny it almost never matters.
Specifically, on Python versions that support decorator syntax, the one difference is that the second version passes the original function directly to
staticmethod, while the first version stores the original function to
a and then looks up the
a variable to find the argument to pass to
staticmethod. This can technically matter in very weird use cases, particularly with metaclasses, but it'd be highly unlikely. Python 2 doesn't even support the relevant metaclass feature (

For example: the code mentioned below can only read the data from one file , how do I replicate this to multiple rows ?

Use a loop. Basically you put your main code into a function (easier to read) and create a list of filenames. Then you iterate over this list, using the values from the list as argument for your function:
Note: I didn't check your scraping code, just showing how to loop. There are also way more efficient ways to do this, but I'm assuming you're somewhat of a Python beginner so lets keep it simple to start with.

The goal is to take a set of jpg/tif images and convert them into 1 text-searchable PDF. I am using Python's PyPDF2 and pytesseract to accomplish this; however, I am unable to find a method of combining these pages without saving each page as its own PDF. Turns out some of these sets could be 1k-10k pages so saving each page individually is unfortunately no longer feasible ... here's what I've got so far:...

You need to use BytesIO:
I am trying to put together a script to fix PDFs a large number of PDFs that have been exported from Autocad via their DWG2PDF print driver.
When using this driver all SHX fonts are rendered as shape data instead of text data, they do however have a comment inserted into the PDF at the expected location with the expected text.
So far in my script I have got it to run through the PDF and insert hidden text on top of each section, with the text squashed to the size of the comment, this gets me 90% of the way and gives me a document that is searchable.
Unfortunately the sizing of the comment regions is relatively course (integer based) which makes it difficult to accurately determine the orientation of short text, and results in uneven sized boxes around text.
What I would like to be able to do is parse through the shape data in the PDF, collect anything within the bounds of the comment, and then determine a smaller and more accurate bounding box. However all the information I can find is by people trying to parse through text data, and I haven't been able to find anything at all in terms of shape data.
The below image is an example of the raw text in the PDF, the second image shows the comment bounding box in blue, with the red text being what I am setting to hidden to make the document searchable, and copy/paste able. I can get things a little better by shrinking the box by a fixed margin, but with small text items the low resolution of the comment box coordinate data messes things up.
To get this far I am using a combination of PyPDF2 and reportlab, but am open to moving to different libraries....

I didn't end up finding a solution with PyPDF2, I was able to find an easy way to iterate over shape data in pdfminer.six, but then couldn't find a nice way in pdfminer to extract annotation data.
As such I am using one library to get the annotations, one to look at the shape data, and last of all a third library to add the hidden text on the new pdf. It runs pretty slowly as sheet complexity increases but is giving me good enough results, see image below where the rough green borders as found in the annotations are shrunk to the blue borders surrounding the text. Of course I don't draw the boundaries, and use invisible text for the actual program output, giving pretty good selectable/searchable text.
If anyone is interested in looping over the shape data in PDFs the below snippet should get you started.
I am attempting to merge two cells together. The reason for this is due to the fact that every unit under 'Chassis' should be an alphanumeric (ABCD123456) however the PO provided occasionally shifts the last number to the next row (no other data on said row) making the data look like this Example I initially tried to create a statement that looked at the cell, confirmed it was less one number, then would look at the next cell, and merge the two. Never got that to even come close to manifesting any results. I then decided to replicate the data frame, shift the second data frame(so the missing number is on the same row), and merge them together. This is where I am now. Error Msg This is my first real bit of code in Python so I am fairly certain I am doing inefficient things so by all means let me know where I can improve.

Add files to the merger with
merger.append(open(filepath, 'rb')) because PyPDF has some odd internal issues with file reader/writers.

I have been trying to convert some PDFs into .txt, but most sample codes I found online have the same issue: They only convert one page at a time.

You could do this with a
for loop. Extract the text from the pages in the loop and append them to a list.
No vulnerabilities reported
You can use PyPDF2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
