Is there a decorator to simply cache function return values?
Consider the following:
memoization
Does Python intern strings?
In Java, explicitly declared Strings are interned by the JVM, so that subsequent declarations of the same String results in two pointers to the same String instance, rather than two separate (but identical) Strings.
Numpy Pure Functions for performance, caching
I’m writing some moderately performance critical code in numpy.
This code will be in the inner most loop, of a computation that’s run time is measured in hours.
A quick calculation suggest that this code will be executed up something like 10^12 times, in some variations of the calculation.
Python – anyone have a memoizing decorator that can handle unhashable arguments?
I’ve been using the following memoizing decorator (from the great book Python Algorithms: Mastering Basic Algorithms in the Python Language … love it, btw).
