We all love using Python's `zip()` function to loop through multiple lists at the same time. But here is a silent bug waiting to happen: by default, if your lists are of different lengths, `zip()` will quietly stop at the end of the shortest list, completely ignoring the extra elements in the longer one.

Starting in Python 3.10, you can pass the `strict=True` argument (like `zip(names, ages, strict=True)`). This forces Python to raise a `ValueError` if the iterables aren't of equal length. It's a tiny addition that saves you from hours of debugging silent data omissions down the road.
