Below are few major features of Python Pyramid
Q1. Explain what is Python Pyramid?
Python Pyramid is a microframework to write down web applications easily. Pyramid belongs to Python 2 and Python 3. Pyramid supported by Python enables the development of complicated and complex software with minimum effort.
Q2. Enlist major features of Python Pyramid?
The major features of Python Pyramid are
Q3. What are Predicates in Python Pyramid?
Predicates in Python Pyramid are questions that return true or false. They also shorten the situations where view or routes are called. Moreover, predicates match the callable view with the home route and posts to the requests by HTTP.
Q4. Enlist few pros and cons Python Pyramid?
Here are a few pros and cons of Python Pyramid Framework:
Cons of Python Pyramid are:
Q5. What are function decorators in Python Pyramid?
Function decorators in Python Pyramid accept a function as the only parameter and also returns a function. A function decorator is useful to use the functionality within the same code repetitively. They are also helpful in the attachment of the data or attributes to the functions. Function decorators remove the redundancy in the Python pyramid.
In other words, it is a function that accepts a function in the form of argument and departs another function as a return value.
Q6. What are renderers in Pyramid?
Renderers in Pyramid are used in place of a pyramid response interface when the latter cannot implement and construct a response. A renderer is associated with the call of the View through View Configuration (view_config()). If a view cannot return an object for a response, the renderer will convert the result to a response of the developer.
When a renderer is used, the return must be compatible with that particular type of renderer. Else an error may result during view invocation. There are several types of renderers present in Pyramid.
They are Built-In Renderers like:
Q7. How to install Python Pyramid using Pip command?
Q8. Enlist few inbuilt renders of Python Pyramid?
Q9. What are ZPT Templates?
Zope Page Templates is a package of Python that employs Templates for the Page in Zope but operates outside Zope. There is no need to install ZPT templates to implement it. ZPT can be used in reporting frameworks, web apps, and documentation systems. ZPT templates derive their namespace from the database of Zope. The namespace is populated in ZPT by producing an own template class for the page and overriding it by one key method.
The file is inserted into the ZPT instance by using the write() method. This creates a namespace for the template and needs to be rendered along with the context.
Q10. How to use ZPT macros with Python pyramid?
To use ZPT macros within Python Pyramid, the macro template should be available near the rendered template just bypassing the macro template into the latter. To insert all the macros inside a view and then passed onto a rendered template, just add:
macros = get_renderer('templates/main_template.pt').implementation().macros
The above should be added to the first code of the sample and extended to the returned dictionary.
