Day 14 : Web Scraping using python (Instagram Image downloader)

-
Hey guys,

Previously we learn web scraping using python for static websites.

Today we will learn about web scraping using python for dynamic websites.
To automate process like downloading images, placing an order or anything on the web can be done by web scraping.

We require libraries like selenium and beautifulsoup

Selenium: 
Selenium Python bindings provides a simple API to write functional/acceptance tests using Selenium WebDriver. Through Selenium Python API you can access all functionalities of Selenium WebDriver in an intuitive way.
Selenium Python bindings provide a convenient API to access Selenium WebDrivers like Firefox, Ie, Chrome, Remote etc. The current supported Python versions are 2.7, 3.5 and above.
This documentation explains Selenium 2 WebDriver API. Selenium 1 / Selenium RC API is not covered here.

How to install?
pip install selenium

Instagram Image Downloader

Read Readmd file

from selenium import webdriver
Import webdriver from selenium, this used open browser depends on browser.

webdriver = webdriver.Chrome()
This will open chrome web driver.(open chrome browser)

from time import sleep
sleep(2)
Import sleep function from the time module, sleep delay the working.

webdriver.get('https://www.instagram.com/accounts/login/?source=auth_switcher')
This will open a specified URL in the browser.

username = webdriver.find_element_by_name('username')
As the name suggest, find element by name , we know websites are in html so this function find that element with specified name in full website.

username.send_keys('username')
Fill that text filed with a specified username  (depends on your username on instagram) 

button_login = webdriver.find_element_by_class_name("y3zKF")
As the name suggest, find element by class name , we know websites are in html so this function find that element with specified class name in full website.

button_login.click()
Click on button.

soup = BeautifulSoup(webdriver.page_source, 'html.parser')
Yesterday we learn about Beautifulsoup, same here we pass our page source and convert to html.

allimages = soup.select('img')
this will select all image tags. or in other words, you can say all images.

img_data = rq.get(img_link).content
As we have img_link , request module is used to GET that image link and content(i.e image).

with open("insta/" + str(index + 1) + ".jpg", 'wb+') as f:
f.write(img_data)
basically here we save our images, we know images are in jpg or jpeg or png format and we have save these file with those extension at write location.
wb+ : as images are in binary format.


That's it you get whatever images you want.
just remember one thing, you have to follow that person or that personal profile is public.

Hey guys, previously we learned about turtle graphics design. Today we will learn about the library pandas which is used for data manipulation and cleaning. What is pandas?  NO not forest or zoo panda. Pandas is a high-level data manipulation tool developed by Wes McKinney. It is built on the Numpy package and its key data structure is called the DataFrame. DataFrames allow you to store and manipulate tabular data in rows of observations and columns of variables. Why Pandas are used? Pandas  is  used   for data manipulation, analysis, and cleaning.  Python pandas  is well suited for different kinds of data, such as Tabular data with heterogeneously-typed columns. Ordered and unordered time series data. How to use Pandas? Pandas is not built-in library so you have to install it. pip install pandas Let's play with pandas How to import? >>> import pandas as pd Same as we import all other libraries Code: >>> dic={...

News website using Flask and news API - Working with templates : Part 5

Hey guys, Today we will display data on the webpage from API. app.py from flask import Flask, render_template,url_for, request, redirect import requests as rq # intialise data of lists. app = Flask(__name__) @app.route('/') def index():               api_key="Your_API_Key"     url="http://newsapi.org/v2/top-headlines?country=in&apiKey="+api_key     data=rq.get(url)     data=data.json()     articles=data["articles"]       return render_template('index.html',articles=articles) if __name__=="__main__":     app.run() render_template -  Generating HTML from within Python is not fun, and actually pretty cumbersome because you have to do the HTML escaping on your own to keep the application secure. Because of that Flask configures the  Jinja2   template engine for you automatically. To render a template you can use the  render_template() ...

Day 9 : Encapsulation and polymorphism

-
Image
Hello Guys, previously we learn about constructor and inheritance and basics of python. Today we learn about  encapsulation and polymorphism. Encapsulation Encapsulation is   wrapping data and the methods that work on data within one unit.  This puts restrictions on accessing variables and methods directly and can prevent the accidental modification of data. To prevent accidental change, an object’s variable can only be changed by an object’s method. Those type of variables are known as  private varibale . Protected members Protected members (in C++ and JAVA) are those members of the class which cannot be accessed outside the class but can be accessed from within the class and it’s subclasses. Public, private and protected keyword But To accomplish this  in Python, just follow  the convention  by prefixing the name of the member by a  single underscore “_” . Code : class Base:    ...
