A: How to group a flat list of attributes into a nested lists? You could create a dictionary to map each attribute to its respective list of items. Then you get the dictionary values to create the final list. Something like this: ```python import re pattern = re.compile(r'attr\d+') just to simulate a "file" file = [ 'attr1 apple 1', 'attr1 banana 2',... (more) |

A: How to log first n lines of a stack trace in Java? It's not clear where this stack trace comes from (either from an exception or the current thread), but it doesn't matter, the way to do it is the same. Both `Exception`'s and `Thread`'s have the `getStackTrace()` method. For the current thread, you can use `Thread.currentThread().getStackTrace()`,... (more) |

A: How to delete a remote branch in git? The other answer already provides the more straighforward solution (`push` with `--delete` option). But there's an older syntax that also works: ```bash git push : ``` Note that there's the `:` character before the branch name. Example: ```bash git push origin :my-branch ``` This ... (more) |

@#64628 It depends on what data the application considers "valid". If I want to be very strict and allow, let's say, only "valid text in a specific set of languages" (or anything closer to that), preventing zalgo text would be a good start, as it wouldn't allow lots of non-sense gibberish (it won't p...

@#64628 You suggested an alternative that leads to the same problem, I just thought this was worth mentioning (not only for you, but for any future readers).
Otherwise, one could read this and think that your solution would avoid the problems caused by a forced push (which is not the case).

@#64628 This doesn't eliminate the problem. Let's suppose the remote has 3 commits:
```
A <-- B <-- C (main)
```
And suppose that lots of people already pulled it (so they all have the 3 commits in their local repos).
If I reset main to commit A (either by force push or directly in the ser... (more) |

If the previous commits (the ones that got lost after `reset`) were already pushed, you can't avoid a forced push.
The only way to avoid it, AFAIK, is to not rewrite history that's already pushed (don't `rebase`/`reset` if it affects already-pushed commits). Instead, you could `revert` the commits... (more) |

Actually, this solution is not restricted to `main`, as it works for any branch.
Regarding `push --force`, just [be aware of the risks before you do it](https://www.gitkraken.com/learn/git/problems/git-push-force#the-risks-of-git-push-force). (more) |

A: How to overwrite lines of STDOUT in Python? The solution proposed by the other answer works, but there's a corner case. If the last message is shorter than the previous one, you might not get what you want. Example: ```python print("this is some text", end="\r") print("abc") ``` Testing this in a Linux terminal, the output is: ```n... (more) |

To shift the elements, you could also use `System.arrayCopy` as below:
```java
int array[] = // some array
int indexToRemove = // index to be removed
int newSize = array.length - 1;
System.arraycopy(array, indexToRemove + 1, array, indexToRemove, newSize - indexToRemove);
// then you can do a... (more) |

Complementing the answer from @#53034 below, if removing is a common operation that needs to be done lots of times, consider using a `List` instead of an array. (more) |

I didn't add this to [my answer](/posts/289289/289295#answer-289295), but one of the reasons *could be*: most commands manipulate the current branch you're working on (`add`, `commit`, `revert`, `status`, `log`, `rebase`, etc), and making `merge` work different would be confusing in that matter.

A: Why is git merge from rather than to? I can't speak for the people who designed it, but I guess it was made this way because you can merge multiple branches all at once. Let's say I've created multiple branches: ```none C---D => b1 / / E---F => b2 | / A--B--G--H => master \ ... (more) |

In some languages, the assignment also yields a value. For example, in JavaScript `console.log(sum = a + b + c)` will assign the value of `a + b + c` to `sum` and yield its value, so `console.log` will print it. In this case, the whole thing `sum = a + b + c` would also be considered an expression? (more) |

As a side note, the documentation calls it ["Old string formatting"](https://docs.python.org/3/tutorial/inputoutput.html#old-string-formatting).

`getSeconds`, `getMinutes` and `getHours` are functions (actually methods, but anyway), and they need to have parenthesis to be called - so change them to `getSeconds()`, `getMinutes()` and `getHours()`, and it'll work: https://jsfiddle.net/7tar9uvw/

One idea to make it easier to find: the line that was changed has a different highlighting, which means the system *already knows* that the difference is on that specific line. Maybe it could show only that line (or have an option to toggle between "show all... (more) |
