Python Pyramid makes it quite easy to write web applications. One can start with kind of small "hello world" alike request or response web app. While learning, one can go ahead with complex programs. As the application gets going, Pyramid offers several features that make writing complex and big software with minimal effort. All versions of Python support Pyramid to works in.
Python Pyramid is an open source web framework WSGI based on the MVC (Model-View-Controller) architectural pattern. Developers of Pyramid dive to Pyramid's descriptive documentation or they can browse the large API references. Pyramid has plenty of resources to choose from. For example, Extending Pyramid is a filterable and curated list of packages, add-ons, and applications constructed to work along with Pyramid.
Pyramid also has some fantastic official project documentation on its official site. Other resources are more difficult compared to Pyramid web frameworks such as Flask and Django, but there are so many tutorials there to learn Pyramid if one chooses to build web applications using Pyramid.
Here we give 10 questions, which are very useful while going for a Python Pyramid Interview.
Function Decorators: Pyramid on all occasions is written with help of Python. All the features known and easy to use in the Python language, like the function decorators, are also available to Pyramid developers. The functions have a decorator called @view_config which also has a route assigned to it and is named done.
Predicates: A question which gives either true or false and which also shortens the collection of situations in which routes or views can be called. In such situations, we use predicates to limit matching of a callable view to a route name of home and to the post HTTP requests.
Many arguments, which are supplied at the time of view configuration are predicate arguments. View predicate arguments are used at the time of view configuration and are used to summarize the set of situations in which view lookup can find a particular view callable.
View configuration often predicates attributes as a vital part of view configuration that allows the view lookup subsystem to search and implement the most appropriate view. The higher the number of predicates attributes being present in the view’s configuration, the more and more specific it becomes that the situations need to be before the registered view callable will be called. The lesser the number of predicates being supplied to a particular view configuration, more likely it will be that the associated view callable will be called.
However, this is no way means that Pyramid stops looking whenever it finds a view registration with predicates that don’t match. If one collection of view predicates is not matching, the next most eligible view is consulted for predicates and like this until a view is found, or no view can be attached with the request. The first view consisting of the set of predicates all of which match the requests of the environment will be called.
