Overview of Scrapy

Scrapy is a Python framework for large scale web scraping. It gives you all the tools you need to efficiently extract data from websites, process them as you want, and store them in your preferred structure and format.

As diverse the internet is, there is no “one size fits all” approach in extracting data from websites. Many a time ad hoc approaches are taken and if you start writing code for every little task you perform, you will eventually end up creating your own scraping framework. Scrapy is that framework.

Scrapy supports both versions of Python 2 and 3. If you’re using Anaconda, you can install the package from the conda-forge channel, which has up-to-date packages for Linux, Windows and OS X.

To install Scrapy using conda, run:

conda install -c conda-forge scrapy

start first project

scrapy startproject firstproject

Decorator in Python - Simplified

By definition, a decorator is a function that takes another function and
extends(/decorates) the behaviour of the latter function without explicitly modifying it.

Let see how we can apply decorators for Functions or Methods

Level I:


We might heard the term, 'sending a function as a parameter to another function'

Practical Example:

def firstFun():
print ("I am the firstFun")

def secondFun(inp): # we are receiving a function(inp=furstFun) as a parameter
inp()
print (" I am the secondFun")

secondFun(firstFun)

Output:
I am the firstFun
I am the secondFun

Observation from the output:
We sent one function(firstFun) to another function(secondFun) as a parameter, and
it helps to utilize that function(firstFun) according to the need.

Level 2:
Now we are going to see the same functionality but pythonic way(Decorator)
def secondFun(inp):
inp()
print (" I am the secondFun")

@secondFun
def firstFun():
print ("I am the firstFun")

Output:
I am the firstFun
I am the secondFun

*** That's it, Now you have done with what & how about Decorators in python***

Now, Again to the definition of the decorator,
By definition, a decorator is a function that takes another function and
extends the behaviour of the latter function without explicitly modifying it.

From our example program,
we are sending firstFun to secondFun and according to the need, we can add more behaviour along with
the original function(firstFun) without modifying it(firstFun)

Today we’d like to share a simple morphing page transition effect with you. The idea is to morph an SVG path while moving an intro page up, creating an interesting, flowy look. For the animations we use anime.js and for some letter effects we use Charming. In the demos we use an “intro transition” in order to showcase the effect, but that’s of course only one of the many use cases for this kind of page transition.

Attention: For the demos use some modern properties like CSS Flexbox and CSS variables without a fallback, so please view them in a up-to-date browser.

The structure that allows us to move the shape along with the intro content, looks as follows:

The fixed content lies beneath the intro content, and once we move the intro content up, it gets revealed. At the same time we morph the SVG path into the one defined in the pathdata:id. When creating the two paths, one needs to make sure that they both have the same amount of points so that the morphing happens smoothly.
