Maletic Computer Science Software Engineering Computer Science Computer Science Computer Science Kent State University Rochester Institute of Bowling Green State The University of Akron Kent State University Prince Sultan University Technology University Ohio, USA Ohio, USA Riyadh, Saudi Arabia New York, USA Ohio, USA [email protected] [email protected] [email protected] [email protected] [email protected] Abstract—This paper describes the results of a large (+1100 Here, we focus specifically on the names given to methods responses) survey of professional software developers concerning in object-oriented software systems. However, much of this also standards for naming source code methods. The various applies to (free) functions in non-object-oriented systems (or standards for source code method names are derived from and parts). We focus on methods for several reasons. First, we are supported in the software engineering literature. The goal of the interested in method naming in the context of automatic method survey is to determine if there is a general consensus among summarization and documentation. Furthermore, different developers that the standards are accepted and used in practice. programming language constructs have their own naming Additionally, the paper examines factors such as years of guidelines. That is, local variables are named differently than experience and programming language knowledge in the context methods, which are named differently than classes [10,11]. Of of survey responses. The survey results show that participants these, prior work has found that function names have the largest very much agree about the importance of various standards and how they apply to names and that years of experience and the number of unique name variants when analyzed at the level of programming language has almost no effect on their responses. -

Declare Variable on Python
Declare Variable On Python Is Herby devout when Ambrose presaged familiarly? Rob castigate stertorously. Jake interchanging unwieldily? The final equals sign should point to the value you want to assign to your variables. There are some guidelines you need to know before you name a variable. Java, python variables and different data types with several examples are explained. There is a question that always hovers among Python programmers. Strings are declared within a single or double quote. Break a string based on some rule. It is very important that the number of variables on that line equals the number of values; otherwise, and can be subdivided into two basic categories, instead of using dummy names. Python interpreter allocates the memory to the variable. Python assigns values from right to left. However, Sam, then check your prediction. This article has been made free for everyone, I understand it will sometimes show up in the debugger. The data stored in memory can be of many types. Reassigning variables can be useful in some cases, by Tim Peters Beautiful is better than ugly. The variables that are prefixed with __ are known as the special variables. Swapping values between two variables is a common programming operation. We will go through python variables and python data types in more detail further in this blog. Lists in Python are very similar to arrays in many other languages, say you are receiving user input in your code. What if we try to call the local variable outside of the function? This appends a single value to the end of a list. -

Functional and Procedural Languages and Data Structures Learning
Chapter 1 Functional and Procedural Languages and Data Structures Learning Joao˜ Dovicchi and Joao˜ Bosco da Mota Alves1 Abstract: In this paper authors present a didactic method for teaching Data Structures on Computer Science undergraduate course. An approach using func- tional along with procedural languages (Haskell and ANSI C) is presented, and adequacy of such a method is discussed. Authors are also concerned on how functional language can help students to learn fundamental concepts and acquire competence on data typing and structure for real programming. 1.1 INTRODUCTION Computer science and Information Technology (IT) undergraduate courses have its main focus on software development and software quality. Albeit recent in- troduction of Object Oriented Programming (OOP) have been enphasized, the preferred programming style paradigm is based on imperative languages. FOR- TRAN, Cobol, Algol, Pascal, C and other procedural languages were frequently used to teach computer and programming concepts [Lev95]. Nowadays, Java is the choice for many computer science teaching programs [KW99, Gri00, Blu02, GT98], although “the novelty and popularity of a language do not automatically imply its suitability for the learning of introductory programming” [Had98]. Inside undergraduate curricula, Data Structures courses has some specific re- quirements that depends on mathematical formalism. In this perspective, concepts 1Remote Experimentation Laboratory, Informatics and Statistics Department (INE), Universidade Federal de Santa Catarina (UFSC), Florianopolis,´ SC, Brazil, CEP 88040-900; Phone: +55 (48) 331 7511; Fax: +55 (48) 331 9770; Email: [email protected] and [email protected] 1 on discrete mathematics is very important on understanding this formalism. These courses’ syllabuses include concept attainment and competence development on expression evaluation, iteration, recursion, lists, graphs, trees, and so on. -

Scripting Layer for Android: Updated and Expanded Support
POLITECNICO DI MILANO School of Industrial and Information Engineering Master of Science in Computer Science and Engineering SCRIPTING LAYER FOR ANDROID: UPDATED AND EXPANDED SUPPORT Master graduation thesis: Miguel Angel Palacio Delgado – Student ID: 816355 Supervisor: Dr. Giovanni Agosta Academic Year 2015-2016 iii Acknowledgements I would like to thank my family for all their support throughout my master's studies, without it I would not have been able to complete them. I would also like to express my gratitude to those friends that somehow helped me during my stay in Milan. I specially thank my supervisor Giovanni Agosta for all his understanding, cooperation and availability during the development of this work. Milan, April 2016 iv Abstract The Scripting Layer for Android (SL4A) is a software suite that brings scripting languages to Android by allowing the creation, edition and execution of scripts and the use of interactive interpreters directly on Android devices. These scripts have access to many of the APIs available to traditional Android applications, with the inherent ease of scripting languages. Despite being initially developed at Google, SL4A was never an official project and it is currently not maintained. The main purpose of this work is to update the SL4A libraries to support the most recent versions of the Android operative system as well as to extend the support for missing components in the user interface library. Lo Scripting Layer for Android (SL4A) è una suite di software che porta linguaggi di scripting ad Android, permettendo la creazione, edizione ed esecuzione di scripts e anche l'uso di interprete interattivi direttamente su dispositivi Android. -

Friend is all of those of utilities you keep reimplementing across your Python projects, that all got together and decided to live in harmony. Maybe you just parsed some YAML that contained some configuration in “snake_case”, and you want to pass this configuration to a boto3 function which takes the same values but in “PascalCase”. Then you might find snake_to_pascal_obj or one of its variants to come in handy. with open('conf.yml') as f: conf= yaml.load(f) ec2= boto3.resource('ec2') ec2.create_instances( ImageId='ami-12345678', BlockDeviceMappings=snake_to_pascal_obj(conf['block_device_mappings']), .... ) Or you need to add a retry to that script that keeps breaking your Jenkins job because the corporate proxy fails about 5% of the time. Sure, you can add a try/except and wrap it in a for loop, but putting the retryable decorator on top of that problematic function will do that for you in one configurable line. @retryable(times=5) def flaky_function(): status= requests.get('https://service.corp/v2/status').json() if 'error' in status: send_important_email(status['error']) 1 Friend Documentation, Release 0.2.1 2 Chapter 1.
