Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...
Refurbishment (electronics) In electronics, refurbishment is the practice of restoring and testing a pre-owned electronic device so that it can be re-sold. Refurbished electronics are therefore pre-owned electronic devices (usually smartphones, tablets, or laptops), that have been tested by a reseller to confirm that they are fully working.
Python 3.0 broke backward compatibility, and much Python 2 code does not run unmodified on Python 3. [34] Python's dynamic typing combined with the plans to change the semantics of certain methods of dictionaries, for example, made perfect mechanical translation from Python 2.x to Python 3.0 very difficult. A tool called "2to3" does the parts ...
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [73] and metaobjects). [74] Many other paradigms are supported via extensions, including design by ...
Boilerplate code. In computer programming, boilerplate code, or simply boilerplate, are sections of code that are repeated in multiple places with little to no variation. When using languages that are considered verbose, the programmer must write a lot of boilerplate code to accomplish only minor functionality. [1]
A class defines an implementation of an interface, and instantiating the class results in an object that exposes the implementation via the interface. [3] In the terms of type theory, a class is an implementation—a concrete data structure and collection of subroutines—while a type is an interface. Different (concrete) classes ...
Spaghetti code is a pejorative phrase for difficult-to-maintain and unstructured computer source code. Code being developed with poor structure can be due to any of several factors, such as volatile project requirements, lack of programming style rules, and software engineers with insufficient ability or experience.
In computer programming, a code smell is any characteristic in the source code of a program that possibly indicates a deeper problem. [1][2] Determining what is and is not a code smell is subjective, and varies by language, developer, and development methodology. The term was popularized by Kent Beck on WardsWiki in the late 1990s.
