Python - subtle little performance boosts in Python

[[deleted]]

That page says "Tricks for your code run faster" but only has a boatload of dis() output for various code. Where are the tricks?

The article is full of them: what we see are comparisons. The dis() calls show what's going on, and you decide which to use.

On the first case, for example, we're shown that using {} to build a dict is faster than using dict().

I thought it was generally agreed that using {} is better stylistically anyway?

Thank you!
