If not, the function is evaluated, and another entry is added to the lookup table for reuse. Lazy evaluation is difficult to combine with imperative features such as exception handling and input/output, because the order of operations becomes indeterminate. The opposite of lazy evaluation is eager evaluation, sometimes known as strict evaluation.
Introduced in Python 2.2 as an optional feature and finalized in version 2.3, generators are Python's mechanism for lazy evaluation of a function that would otherwise return a space-prohibitive or computationally intensive list. This is an example to lazily generate the prime numbers:
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
The main advantage gained in employing a lazy learning method is that the target function will be approximated locally, such as in the k-nearest neighbor algorithm. Because the target function is approximated locally for each query to the system, lazy learning systems can simultaneously solve multiple problems and deal successfully with changes ...
The functions determining the highest score or longest running time of the n-state busy beavers by each definition are Σ(n) and S(n) respectively. [4] Deciding the running time or score of the nth Busy Beaver is incomputable. [4] In fact, both the functions Σ(n) and S(n) eventually become larger than any computable function. [4]
Laura Loomer, a staunch ally of President-elect Trump and far-right activist, suggested that some Republicans in Trump’s circle don’t want to cross billionaire Elon Musk. “It sounds like ...
For computer log management, the Common Log Format, [1] also known as the NCSA Common log format, [2] (after NCSA HTTPd) is a standardized text file format used by web servers when generating server log files. [3] Because the format is standardized, the files can be readily analyzed by a variety of web analysis programs, for example Webalizer ...
