Moje biuro (...) miało być zamknięte, ale miałem komputer domowy i niewiele do roboty. Postanowiłem stworzyć interpreter dla nowego języka skryptowego, (...) który byłby atrakcyjny dla hakerów Unix / C. • Guido van Rossum (ur. 1956 Haarlem, Holandia) • nazwa – Latający Cyrk Monty Pythona • początki – lata 90.

For Python version 3 This book will teach you to use Python version 3. There will also be guidance for you to adapt to the older and more common Python version 2 in the book. Who reads A Byte of Python? Here are what people are saying about the book: This is the book that got me into programming almost a decade ago. Thank you @swaroopch. You changed my life. -- Stefan Froelich I am writing this email to thank you for the great help your book has done for me! It was a really good book that I enjoyed thoroughly. As a 15 year old who has never done programming before, trying to learn Python online was difficult and I couldn't understand anything.

Peps & the zen of Python Why (not) Python Why not ? - You need realtime ( < µsec) but check Viper ( http://doc.viperize.it ) - You have very little RAM but Tiny Python = 64K & VM of micropython = 2,4K - You have very little CPU but there are implementations even for Arduino - Compiled code is your God, Interpreted code is your Evil. - You need protected code - You need compatibility with bullshit managers (justification + job-protection) > technical rationality Why (not) Python Why ? - Very high-level, short yet very readable, intuitive syntax Easy to learn (pseudo-code-like) (no funky WTF characters series...follow my eyes). Great for non-trivial business-logic (You still understand while your client is long time lost in his own specs) Maintainable even after 150 last-minute changes (Don't tell me it never happens) Maintainable even after 10,000 lines of code (Maintenance = €) - Totally Free & Truly Open Source (PEPs, PSF, ...) - Portable on most OS, including embed systems, including GUI lib - Many different uses: Small helper-scripts (Any Sys-admins in the room ?)

    International Journal of Engineering and Advanced Technology (IJEAT) ISSN: 2249 – 8958, Volume-9 Issue-3, February, 2020 A Correlative Scrutiny on two Programming Dialects: RUBY Vs PYTHON Sarath Chandran, Kochumol Abraham Abstract: The two most dominant rising programming dialects Ada. Today Ruby has grown to be one of the most popular in reality, Ruby and Python have many features in common. web development language using Ruby on rails. High-level object-oriented coding, interactive shell, standard There is more than one way to do the same thing (Ruby libraries, persistence support are some of the common features of principle) which interprets [13] as Code flexibility which Python and Ruby. However, both vary in their approach to solve is one of the major advantage of Ruby [41]. Programmer can problems because of their syntax and uses. Power of a language define their on syntax for coding. It makes programming is based on the libraries and popularity defines the frameworks that have been used. This research paper primarily focuses on more fun which results in its popularity among programmers the frameworks and libraries of Ruby and Python. Ruby on Rails [30]. Python and Ruby are two competing programming is one of the most powerful framework of Ruby and Django for languages today. Both languages are similar and at the same python. Python is used for many purposes beyond web time they have their own uniqueness [23][28]. Ruby and development such as data science and machine learning Python [5],[8] works on distinctive platform inclusive of computations. A spike in popularity is seen for both Ruby and Mac OS, Windows and various versions of linux [26][27].
