It decides in the event the their enters is actually constants or of comparable viewpoints

At core out-of optimizations, there’s a you will need to influence the values from variables on run some time forecasts out of assignments. A phrase, elizabeth.grams. a component changeable accessibility, an expensive procedure, is generally ongoing over the component of the setting range and next there should be none if any frequent module variable look-up.

It is not complete

Imagine age.grams. the newest component attribute __name__ and that almost certainly is just actually comprehend, thus their worth is predict so you’re able to a steady sequence known within harvest date. This may following be used given that enter in for the ongoing foldable.

From modules features, just __name__ is now indeed optimized. And additionally you can easily might possibly be about __doc__ . Afterwards, this could improve due to the fact SSA are lengthened to help you module variables.
