And your code became less understandable.

You have saved 1.4 *seconds*. What is the normal running time for this
app with 0.5M records? What is 1.4 seconds as a percentage of that?

Please consider that you are barking up the wrong gum tree. Competing
with a C app on speed is not something that experienced Python
programmers would take on lightly.

Talk to your colleague about some of these factors: time to write code,
robustness, clarity, ease of maintenance.

Cheers,
John
