What is first-coded-temperature-converter?

First-Coded-Temperature-Converter is a simple command line program written in Python that converts a temperature between Celsius, Fahrenheit, and Kelvin. You run it by typing a single command in a terminal, and it walks you through entering a temperature and choosing which units to convert between. The program is built to handle bad input gracefully. If you type something that isn't a valid number, it catches the error using Python's try and except pattern instead of crashing, and asks you to enter the value again. This same re-prompting behavior appears at every step of the program, whether you are entering the temperature itself, choosing a unit, confirming your choice, or deciding whether to run another conversion. Structurally, the program uses a loop inside a loop: a small inner loop handles validating and confirming a single conversion, and that sits inside one larger loop that lets you keep converting more temperatures without restarting the program each time. The author also introduced flags, which are variables set inside the inner loop and then checked afterward so the outer loop knows what happened and what to do next. According to the README, this is a personal learning project built by someone named Martinez who is teaching themselves to code, with the general idea for a temperature converter coming from a YouTube tutorial by Bro Code, though the author states they wrote and debugged all the code themselves. They mention using Claude as a tutor and consulting online forums to understand concepts like nested loops and flags before implementing them independently. The README notes the project took about eight hours across two sessions to complete, and that it is the author's most complex project so far, though it also contains repeated code that does not yet follow the DRY, or don't repeat yourself, principle, since the author has not learned how to write functions yet. The author states they plan to become a software developer or work in cybersecurity.
