| 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... (more) |

A: Remove entries by two-column ID everywhere, that meet a condition somewhere Answer After re-encountering this problem and searching for a solution with a less generic "pandas check if column pair is found in other df" (forgetting I had previously encountered this problem altogether), I found some inspiration that led me to a solid solution. It is fastest, and most c... (more) |

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. (more) |

It's a good question. I would expect there to be a parameter for this in the `mean()` function. (more) |

How to compress columns of dataframe by function Problem How can I compress each column of a dataframe to the output of a function (i.e., mean), preserving columns?

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). (more) |

| 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... (more) |

Either way it's going into latex, .png or table. I'm open to both, but only a solution that lets me export to that format without me manually re-entering data. (more) |

Nice, this also works if I store the plot in a variable for saving:
```py
plot = df.plot.bar()
plot = plot.axvline(x=2.5, ymin=0, ymax=1)
plot.get_figure().savefig("busy_bar.png")
