Here in this post, we presented a very easy python code to convert any image into sketch. First of all you need to install OpenCv Library: pip install    opencv-python Python Code: from cv2 import cv2 image=cv2.imread("E:/Drive/msc/anshucln/Images/420.jpg") gray_image=cv2.cvtColor(image,cv2.COLOR_BGR2GRAY) inverted=255-gray_image blurred=cv2.GaussianBlur(inverted,(21,21),0) invertedblur=255-blurred pencilsketch=cv2.divide(gray_image,invertedblur,scale=256.0) cv2.imwrite("E:/Drive/msc/anshucln/Images/42111.jpg",pencilsketch)

 Web Scraping is the process of retrieving the web information automatically using bots. Here in this tutorial, we used Python. IDE used: Visual Editor. Programming Language: Python. Steps to perform: Step 1:  Open the Visual Editor or any editor, and Install the following dependencies: pip install requests pip install bs4 pip install html5lib Step 2: Get the HTML Step 3: Parse the HTML Step 4: HTML Tree Traversal Complete Code #Step 1 import  requests from  bs4  import  BeautifulSoup url= "https://phdtalks.org" # step2: Get the HTML r=requests.get(url) htmlcontent=r.content #print(htmlcontent) # step3: Parse the HTML soup=BeautifulSoup(htmlcontent,  'html.parser' ) #print(soup) # It will print all the html code of your website. # step 4: HTML Tree traversal # commonly used objects here: Tag, NavigableString, BeautifulSoup, Comment title=soup.title  # It will print the title of website. print (title) # Get all the paragraphs from the page paras=soup.find_all( 'p&#

head (): It shows the first five rows of the dataset. shape : It shows the total rows and columns of the dataset. index : It shows an index of the data frame. columns : It shows the name of each column dtypes : It shows the data type of each column unique : It provides the unique values. It can be applied on a single column only. nunique: It shows the total number of unique values in a column. It can also be applied on a whole  data frame. count : It shows the total no of non-null values in each column. info : it provides the basic information about the data frame. I have applied all the above commands in a data science project. You must also practice these commands. The data set can be downloaded from here . The source code having all the above commands: import pandas as pd data=pd.read_csv('C:/Users/sunny/Desktop/MACHINE LEARNING/python_project/weather.csv') data.head() data.shape data.index data.columns data.dtypes data['Weather'].unique() data.nunique() data.count()

For performing web automation or web scraping using python: Install Selenium using pip command. Download browser driver. Write Python code using any IDE. How to install Selenium using pip command? Open command prompt and type pip install selenium and wait for a while to get it installed. If you are using mac or linux, write pip3 instead of pip. How to Download browser driver? Download browser driver from the internet. Here in my case, I am using driver for Google Chrome. However, you can use other browser also. Go to the https://sites.google.com/a/chromium.org/chromedriver/downloads I am suing Google Chrome 86 version, so i am selecting second option. I am selecting chromedriver_win32.zip, since i am using windows. Extract the driver and place it in the c->proramme File folder for easy access. However, you can place it anywhere in your computer. Copy this path. Write the following python code in an IDE. I am using Visual Editor.   from  selenium  import  webdrive
