A: How can I build a string from smaller pieces? Before attempting this, make sure it makes sense in context. In a few particular situations, it would be better to take a different approach rather than using the normal tools for composing or formatting a string. If the string is for an SQL query, use the SQL library's built-in functional... (more) |

How can I build a string from smaller pieces? Suppose I have some variables like: ```python >>> count = 8 >>> status = 'off' ``` I want to combine them with some hard-coded text, to get a single string like `'I have 8 cans of Spam®; baked beans are off'`. Simply writing the values in sequence only works for literal strings: ```python... (more) |

... Although, as I read these answers, I feel more and more like the concept of a statement is something we usually understand intuitively, and which is much harder to explain than it initially appears. (Expressions still seem fairly straightforward, though.) (more) |

Since 3.8, the `:=` operator in Python allows for assignments that *are* expressions, with some limitations. It seems worth mentioning in that section. (more) |

On Stack Exchange, Stack Overflow is around 15 times the size of anything else, and existed well before the Stack Exchange network came into existence. Codidact, on the other hand, started fresh with every proposed community on equal footing - rather than having a generalist site created as an aftert... (more) |

Of course I am able to answer this question myself; but I have several other self-answered questions in the works, and I want to help set the tone for missing, important reference questions like I have been talking about a bit in Meta. I expect that having this (and similar efforts) as a high quality... (more) |

What are statements and expressions? When I have tried to read technical explanations of the syntax rules for programming languages, and when I am trying to decipher error messages, I often encounter the terms expression and statement. It comes across that these two are related to each other somehow. I understand that these terms hav... (more) |

A: How to compress columns of dataframe by function Conceptually, applying a function along an axis of a `DataFrame` (i.e., applying it to each row or column) inherently produces a `Series`: a two-dimensional result is collapsed to a one-dimensional result, because one-dimensional "lines" of data are fed into a function that produces a scalar value. ...

FWIW, @#8176, the self-answered question you mention in the other thread is a perfect example of what I advocate for in my answer here. Let's do more of that. A lot more. (more) |

A: Questions easily answered by studying a beginner-level book There's still time > This scenario is not yet a problem for this site, but we will get there, since it's a huge problem for Stack Overflow This topic should be separately addressed, too. At time of writing, the main category here has 673 posts (perhaps a few more deleted ones, because I coul... (more) |

A: Automatically install all packages needed A compromise exists between automatically inferring package names (unreliable and potentially dangerous) and writing out an explicit separate `requirements.txt` file: script-running tools such as `pip-run` may offer the ability to parse requirements declared explicitly within the source file itself, ...

When other threads are already expanded and you click "start a new comment thread", you might have to scroll quite some distance to the actual comment submission form. There's a good chance it isn't even on screen at that point, meaning you don't get immediate visual confirmation. The form should app... (more) |

A: How can we grow this community? Never Too Late Due to, shall we say, recent AI-related hallucinations, pretty much everything that was possible PR-wise in 2019 is possible for this site again. People are leaving Stack Overflow and this is arguably the best existing alternative. Opportunity has knocked again, but in a sense it re... (more) |
