Question Can pandas be used as a database backend for persistent storage?
Question What is the current state of the art database app? How does it compare to SQL? Can pandas be used in place of either? If not, is there something that bridges the gap between SQL and pandas or the current state of the art? Context I have become proficient in pandas and have come to...

Comment Post #288074 The problem with this answer is that it will remove cells in every die, when it should only remove cells identified within that die. With your answer, if I find that die 1, cell 9 is bad, I will also be removing die 2, cell 9, which may not be bad.

Comment Post #287884 It's a good question. I would expect there to be a parameter for this in the `mean()` function.

Comment Post #287514 Built-in to pandas. Pandas tends to be feature complete with respect to R. [Here is the function documentation in R](https://search.r-project.org/CRAN/refmans/goeveg/html/cv.html).

Question How can I provide additional information when raising an exception?
Suppose I have some code like: ```py filename = "baddir" print(f"File not found: {filename}.") raise(FileNotFoundError) ``` When the exception isn't caught, the stack trace is printed at the end of the output, right as the program aborts. The `print`ed message could be far above this and is...
