Random. Top 10 Free Courses to Learn Python in Depth - Best of Lot. There is no doubt that Python is currently the world's #1 programming language and the biggest advantage of that is it's bringing more and more people into the programming world.
In recent years, I have seen more people learning Python than any other languages, yes, not even JavaScript. Many of them learning Python to explore some awesome Data Science and Machine learning libraries provided by Python. Some people are also learning Python for web development and there are still many developers who are learning Python for scripting and automating trivial tasks. It doesn't matter why you are learning Python at this moment, it's a great thing in itself that you have decided to learn Python. Even though I am a Java programmer and I have spent all my career coding in Java, I value Python very high for its versatility. How To Code in Python 3.

Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python.
The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. The first exercises work on basic Python concepts like strings and lists, building up to the later exercises which are full programs dealing with text files, processes, and http connections.
The class is geared for people who have a little bit of programming experience in some language, enough to know what a "variable" or "if statement" is. Beyond that, you do not need to be an expert programmer to use this material. This material was created by Nick Parlante working in the engEDU group at Google.

Internet, c’est la culture du TL;DR, donc plutôt je vais faire une petite synthèse des trucs les plus importants du PEP8, comme ça si vous avez la flemme de le lire, au moins vous aurez l’essentiel.
Ce texte liste les règles stylistiques recommandées, invitant toute la communauté Python à écrire un code de la même façon. Je vais également y ajouter des éléments de style qui ne sont pas dedans, mais que j’ai pu constater comme étant les choix les plus courants dans les sources que j’ai pu lire. Espaces Les opérateurs doivent être entourés d’espaces. Il faut faire ceci : Et non: Il y a deux exceptions notables. La première étant qu’on groupe les opérateurs mathématiques ayant la priorité la plus haute pour distinguer les groupes : La seconde est le signe = dans la déclaration d’arguments et le passage de paramètres : On ne met pas d’espace à l’intérieur des parenthèses, crochets ou accolades. Oui : Non : On ne met pas d’espace avant les deux points et les virgules, mais après oui. S Python Class - Google for Education.

Python's name is derived from the television series Monty Python's Flying Circus, and it is common to use Monty Python reference in example code. This language is now one of the most popular languages in existence. This language is now one of the most popular languages in existence. Since 2003, Python has consistently ranked in the top ten most popular programming languages as measured by the TIOBE Programming Community Index.

No whitespace before a comma, semicolon, or colon. Do use whitespace after a comma, semicolon, or colon except at the end of the line. Yes: if x == 4: print x, y x, y = y, x No: if x == 4 : print x , y x , y = y , x No whitespace before the open paren/bracket that starts an argument list, indexing or slicing. Yes: dict['key'] = list[index] No: dict ['key'] = list [index] Surround binary operators with a single space on either side for assignment (=), comparisons (==, <, >, !
Don't use spaces around the '=' sign when used to indicate a keyword argument or a default parameter value. Yes: def complex(real, imag=0.0): return magic(r=real, i=imag) No: def complex(real, imag = 0.0): return magic(r = real, i = imag) Don't use spaces to vertically align tokens on consecutive lines, since it becomes a maintenance burden (applies to :, #, =, etc. Style Guide for Python Code. Code should be written in a way that does not disadvantage other implementations of Python (PyPy, Jython, IronPython, Cython, Psyco, and such).For example, do not rely on CPython's efficient implementation of in-place string concatenation for statements in the form a += b or a = a + b.
This optimization is fragile even in CPython (it only works for some types) and isn't present at all in implementations that don't use refcounting. In performance sensitive parts of the library, the ''.join() form should be used instead. This will ensure that concatenation occurs in linear time across various implementations.Comparisons to singletons like None should always be done with is or is not, never the equality operators.Also, beware of writing if x when you really mean if x is not None -- e.g. when testing whether a variable or argument that defaults to None was set to some other value.
The other value might have a type (such as a container) that could be false in a boolean context! Programmation Python. Apprendre à programmer avec Python/Avant-propos. Un livre de Wikilivres.

C'est aussi une ambitieuse quête menée dans les tréfonds de la connaissance. » Python Documentation contents — Python 2.7.8 documentation. Blenderlounge. Style Guide for Python Code. This document gives coding conventions for the Python code comprising the standard library in the main Python distribution. Please see the companion informational PEP describing style guidelines for the C code in the C implementation of Python [1]. This document and PEP 257 (Docstring Conventions) were adapted from Guido's original Python Style Guide essay, with some additions from Barry's style guide [2]. This style guide evolves over time as additional conventions are identified and past conventions are rendered obsolete by changes in the language itself.
Many projects have their own coding style guidelines. In the event of any conflicts, such project-specific guides take precedence for that project. One of Guido's key insights is that code is read much more often than it is written. A style guide is about consistency. However, know when to be inconsistent -- sometimes style guide recommendations just aren't applicable. Some other good reasons to ignore a particular guideline: Indentation.

It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation. 3.6.3 Documentation.
