A: How to resolve a "ValueError: dimension 't' already exists as a scalar variable" arising when I am using xarray.Dataset.assign_coords()? It seems like what you want to do can be achieved by using ```python data.assigncoords(t=[0.123]) ``` The error message is extremely confusing in this respect, but it seems like the new value for the coordinate must have the same shape as the original coordinate value. In this case, `data.t.sh... (more) |

A: Readable syntax for executing many callables with useful side effects The `map` operation is a typical concept from the functional programming paradigm. However, side-effects are a typical example of something that does not fit functional programming well. As a result, `map` is probably not what you want to use. As an alternative, you can just use the `apply` meth... (more) |

There also exist expressions that perform actions (e.g. the walrus operator `:=` since Python 3.8, or `++i` in C). Would you consider these expressions to be statements as well? (more) |

A: How to compress columns of dataframe by function Since `pandas` uses `numpy` for these computations under the hood, I would have suggested to use `df.mean(keepdims=True)`, but apparently this has been explicitly disabled by `pandas`. However, after looking into the docs, I noticed you should be able to get the desired result as follows (note the... (more) |

Unfortunately, I am not familiar enough with submodules in Git to provide a proper answer, but you should definitely include this information in your question to show what you have tried/done already. (more) |

A: Should we disallow ChatGPT-User crawler (and others) from scraping Software Codidact? A few thoughts from my side (as a ML researcher, without experience in LLMs): 1. I am not sure if it is really useful to block ChatGPT specifically. ChatGPT is only one of many LLMs out there. Blocking only ChatGPT will probably not prevent the data on codidact from being fed into other mo... (more) |

According to the [docs](https://git-scm.com/docs/git-pull#Documentation/git-pull.txt---no-recurse-submodulesyeson-demandno), this should be possible using `git pull --recurse-submodules`. Have you tried that? (more) |

A: How can we grow this community? After a few years of casually using stack-exchange sites and wandering around on coda-dict, I feel there are mainly three components to the quality of the content on each of these sites: 1. the knowledge base 2. the community 3. the game The Knowledge Base I think most answers to this ques...

A: Slicing a dictionary using a string variable Assuming that `dynamicmodel` and `uncertainlibrary` are just (nested) dictionaries and ```python value = '"SCD"' ``` is actually supposed to be a string (note the single quotes here), your code would attempt to add a dictionary to a string, which is indeed not supported. Python would let you k... (more) |

This is not valid syntax in Python, but it could be when combining single and double quotes. (more) |

I thought this would create a duplicate tag. But it indeed seems to delete the existing tag, thanks! (more) |

Stupid, I must have missed that error message. However, I also get it when writing `dec_first = map (subtract 1) . take` even though I am not applying `take` to any arguments in this case. Where does this error come from? (more) |

How to use function composition for applying a function to first elements of a list? Can anyone explain to me why my Haskell function gives rise to a type-definition error? Originally, I wrote the following function to subtract one from the first `n` elements in a list: ```haskell decfirst :: Int -> [Int] -> [Int] decfirst 0 l = l decfirst n (x:xs) = (x-1):decfirst (n-1) xs `...
