A: How to overwrite lines of STDOUT in Python? You can use the carriage return control character `"\r"` to return to the beginning of the line and overwrite text. When using the `print` function you additionally have to make sure not to write the line feed control character (`"\n"`) is not printed. The easiest way to achieve this is probably to... (more) |

A: Regex for simplifying Amazon product URLs The following expression should capture the `{dp|gp}/$ID` part: ```plaintext https://www\.amazon\.com/([gd]p/[A-z0-9]{10}) ``` A quick explanation: - the `\.` are there to match periods only (otherwise it would match any symbol), - `[gd]p` matches either `gp` or `dp`, - `[A-z0-9]{10}` ...

The problem is that it does not really make sense to write an answer about `BitSet` in this general context, since e.g. Python does not really have a data structure like that. This is probably also the reason why I assumed this was a Python and not a Java question.
My point is that by abstracting ... (more) |

Roughly speaking, tensorflow-graph is tensorflow-v1 and tensorflow-eager is tensorflow-v2. I don't think these tags would be that useful. Especially since there are generally not that much tensorflow questions thus far. (more) |

I definitely agree that showing non-working attempts is generally a good thing. I do feel that the non-working attempts should be conceivable from the standpoint of someone who could have this question, however. I just can't imagine that someone would think about tuples in this kind of scenario. (more) |

First of all, I hope it is clear that I did not intend to "attack" your question. I just found the topicality documentation a little ambiguous about this kind of question.
To me, software design/architecture/modelling is one level above the actual algorithm/data structure considerations. On a soft... (more) |

I have no problem with the language-agnostic tag. I think my main issue is that this question feels like it originated from Python and was then artificially generalised to cover all languages (or all languages with a data structure for sets that is implemented by a hashtable). In the end, this questi... (more) |

Are questions about (abstract) algorithms and datastructures considered on-topic? I just noticed this question about data structures in the Q&A. Although algorithms and data structures are often (part of) a solution to a problem when writing software, this question is constructed in a way that aims to leave out the software part entirely. Especially, because I have a strong feel... (more) |

A: Should self-answered Q&A use separate answers for different techniques/approaches (even if there's a caveat that applies overall)? I believe one of the main strengths of Q&A websites is that they provide a more digestible alternative to dense documentation. Especially for programmers who do not yet know how to find/use the documentation for the language that they are working with. The answer (and even the question [^1]) is/ar... (more) |

I agree with @#53398 that this question comes over as too artificial. In the list you linked in the answer to the meta question, you list these top questions. One common aspect of these questions seems to be that they have very short and simple question statements. These questions are popular because... (more) |

A: Best practices to write functions for both execution modes in Tensorflow, eager and graph mode Tensorflow functions should typically work on both eager and graph tensors. This means that you can just use the following implementation: ```python def lintodb(x: float | tf.Tensor) -> tf.Tensor: """ convert signal to noise ratio (SNR) from linear to dB """ return 10. tf.math.log(x) / ...

A: Listen for key events in a CLI app First of all, the standard keystroke for interrupting a CLI program would be `ctrl + C` or whatever the windows equivalent is. Therefore, you will get the most consistent user experience if you use this standard keystroke for interrupting the program (rather than something custom like space). One... (more) |

tensorflow functions should work both on eager and graph tensors. I just tried `10. * tf.math.log(x) / tf.math.log(10.)` and it worked in both settings.
Similarly, you could use `tf.cast(x, dtype=tf.int64)` for the casting function (unless there is a specific reason why you would not want graph tens... (more) |

A: How can I properly type-hint methods in different files that would lead to circular imports? I eventually also found out that the `typing` module has a global variable `TYPECHECKING` that can be used to only import during type-checking. Concretely, the following code for `helpers.py` seems to type-check fine as well. ```python from typing import TYPECHECKING if TYPECHECKING: from ... (more) |

How can I properly type-hint methods in different files that would lead to circular imports? I am writing a Python package where I have two classes in different files that (indirectly) depend on each other. If I wouldn't care about type-hints, there would be no problem, but unfortunately, I do like static type-hinting. Therefore, I need one class for typing the methods of the other and vic... (more) |

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) |

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.
