--- june meeting: intros: - there was at least one new comer and several old timers who decided to show up today, welcome! - we had one open bsd user (that's new...) - one suse user... bob i'm pretty sure... - a ubuntu user, mint, deepin, etc, etc. meeting topic: "Getting Started with Python Programing" - the presentation appears to center around flask which is a popular lightweight python based web framework that does many things - python has packages, which is a collection of python modules - pip is used to install said packages - is a package manager similar to a Linux package manager such as apt-get or yum - virtualenv is a tool to create isolated python environments - this is basically a way to keep from breaking your system python environment and to give you application its own namespace - it is also a package that can be loaded with either pip or the os package manager - python terms - argument - value passed to a function - immutable - an object with a fixed value. immutable objects include numbers, strings and tuples. Example: key in a dictionary - mutable - an object that can change their value but keep their id() - statement - part of a suite or block of code. a collection of if, while or for expressions - class - a template for creating user-defined objects - decorator - a function returning another function, usually applied as a function transformation using the @wrapper - flask - based on werkzeug toolkit and jinja2 template engine - homepage - http://flask.pocoo.org - werkzeug is a WSGI utility for python - jinja2 is used in many python projects, similar to django templates - routes - specific commands are executed by flask when you access a flask router (eg. /dosomething) - templates can be created with logic (such as iteration) in them. - variables can be added to the routes for sending data between client and server - several examples were showed and well all tried very how to explain how decorators work... i'm not sure we did a good job or not because they are mysterious to be honest... - mike showed a simple https example with flask - he then showed some example code that was used to create a simple dropbox-like example - for a simple way to "test" your code try pythonanywhere.com - there is a free tier that allows you to try their service or you can pay for more usage... - after that there was conversation about various other python topics such as the benefits of packaging, requirements.txt, console scripts, pep standards etc. - then we all talked about GitHub and what our favorite GitHub alternative is. - we all voted that gogs was the best in favor of gitlab and Launchpad (not sure if Launchpad even a fair comparison but hey).
