Let’s run this code in IDLE and see what happens.

Your latest code

This output
is much more
understandable.

This program works as expected, and is fine…except that you have to name and create
Sarah’s three variables in such as way that it’s possible to identify which name, date of birth,
and timing data relate to Sarah. And if you add code to process the data for James, Julie,
and Mikey, you’ll be up to 12 variables that need juggling. This just about works for now
with four athletes. But what if there are 40, 400, or 4,000 athletes to process?
Although the data is related in “real life,” within your code things are disjointed, because
the three related pieces of data representing Sarah are stored in three separate variables.
