A few things:

Those lines were specifically introduced as an attempt to fix an earlier error. Here is the one that introduced the 'b' - #1630. It was a proposed solution here - #407. So can you just confirm that the things work as expected and run on windows with the change? I don't understand windows file formats enough to be able to comment.

But the other thing to note is that, as these files are part of the Python sequence, you also need to update with the changes in these files - /assets/python-lessons.zip and python-es-lecciones.zip. There is a different zip file for each python lesson, and IIRC, you'll need to just make sure you update the zip files following the one in which the error appears.

And the 'wb' usage actually appears in several places.…I'm trying to get a list to you. It would be great to be able to grab all of those now.

[walshbr]

This is a list of the files and the instances in the number of times that 'wb' appears in them. Let me know if that doesn't make sense?

[walshbr]

We might have just been pointed to the two files you pinpointed based on where the bugs were reported, but they'll be issues throughout the Python sequence.

Yes, it was checked on Windows. I'll check the zip files. Thanks for noting that!
Regarding the rest of the lessons, all of them are going to be checked: #1885 (comment)

[walshbr]

Awesome - thank you!

Regarding the previous change that added the 'b', I suspect that we trusted the solution proposed by a reader without checking it on Windows 😬
