A guide for astronauts (now, programmers using Git) about what to do when things go wrong.Flight Rules are the hard-earned body of knowledge recorded in manuals that list, step-by-step, what to do if X occurs, and why. Essentially, they are extremely detailed, scenario-specific standard operating procedures. [...]NASA has been capturing our missteps, disasters and solutions since the early 1960s, when Mercury-era ground teams first started gathering "lessons learned" into a compendium that now lists thousands of problematic situations, from engine failure to busted hatch handles to computer glitches, and their solutions.Steps for common operations and actions I want to start a local repositoryWhat did I just commit?I want to discard specific unstaged changesRestore a deleted file Brian #2: Uravelling t-strings Brett CannonArticle walks through Evaluating the Python expressionApplying specified conversionsApplying format specsUsing an Interpolation class to hold details of replacement fieldsUsing Template class to hold parsed dataPlus, you don’t have to have Python 3.14.0b1 to try this out.The end result is very close to an example used in PEP 750, which you do need 3.14.0b1 to try out.See also: I’ve written a pytest version, Unravelling t-strings with pytest, if you want to run all the examples with one file.

It didn’t go well. But perhaps the project is ready for some refactoring. I’d like to try it soon on a more well behaved project.
