What are Bots and what do they do?
Website scraping bots are automated programs (usually written in Python) that extract data from websites. They can be used to gather information from multiple web pages quickly and efficiently. These bots work by sending HTTP requests to a website and parsing the HTML response to extract the desired data. Website scraping bots can be used for a variety of purposes, such as price comparison, market research, and data analysis. You might also have unique requirements within the organisations to use the scrapping bots.
There are many examples of web scrapers that can be used to extract data from websites. Some popular web scraping tools include Beautiful Soup, Scrapy, and Selenium. These tools allow users to write scripts that can navigate websites and extract specific data. For example, a user might use a web scraper to gather product information from an e-commerce site or to collect news articles from a news website. Web scrapers can also be used to monitor websites for changes or to gather data for machine learning models. You can also use the web scrapping bots to create a knowledge centre, or, to access data from the knowledge centre. As I mentioned above, your use case might be specific to your role and organisation.
As a data scientist working with data, it’s often necessary to copy information from one website and paste it into another website. This can be a time-consuming task if done manually, but with the help of Python and JavaScript, the process can be automated and made much more efficient.
What if we mix WebScraping with Machine Learning?
We can create some powerfull apps and insight if we mix WebScraping with Machine Learning. It often gives us a ground to build a continous data stream along with actions – such tools are mostly used in Customer Satisfaction where websites like TrustPilot can be used to preemtively assess customer satisfaction before customers actually respond to the surveys.
Copy data from a website using Python Libraries
One of the most common libraries used for web scraping in Python is BeautifulSoup. It allows you to extract data from HTML and XML files, making it an ideal tool for copying data from websites. In this example, we will use BeautifulSoup to extract data from one website and paste it into another website.
First, we start by installing the BeautifulSoup library using the following command:
pip install beautifulsoup4
import requests url = "https://sourcewebsite.com" response = requests.get(url) html_content = response.content
Once we have the HTML content of the source website, we can use BeautifulSoup to extract the data we need:
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_content, "html.parser")
data = soup.find("div", {"class": "data"}).text
target_url = "https://targetwebsite.com/submit"
post_data = {"data": data}
response = requests.post(target_url, data=post_data)
With these simple steps, you can easily copy data from one website and paste it into another website using Python and BeautifulSoup.
Above code gives you an example on how to extract the data from a page using BS4. However, there are a number of things that I am assuming you already know. For example, I am assuming that you are able to find individual element within the HTML, You know how to unlock HTML if the code is locked, And, You are well versed with the iteration and functions within Python.

Copy the data using JavaScript
Another way to copy data from one website to another is by using JavaScript. This method is especially useful if you need to copy data from a website that requires user interaction, such as filling out a form or clicking a button.
In this example, we will use JavaScript to extract data from one website and paste it into a form on another website.
First, we start by loading the source website in a web browser and using the browser’s dev tools to inspect the elements and find the data we want to extract:
let sourceData = document.querySelector("#sourceData").textContent;
In this example, we use the querySelector method to select an element with the id “sourceData” and extract its text content. You can modify this code to select different elements and data based on text
Next, we navigate to the target website and use the browser’s dev tools to inspect the form and find the input fields we want to paste the data into:
document.querySelector("#targetField").value = sourceData;
In this example, we use the querySelector method to select an input field with the id “targetField” and set its value to the source data we extracted earlier. You can modify this code to select different input fields based on your needs.
Finally, we can submit the form to complete the process of copying data from one website to another:
document.querySelector("#submitButton").click();
In this example, we use the querySelector method to select a submit button with the id “submitButton” and trigger a click event to submit the form. You can modify this code to submit the form in different ways based on your needs.
With these simple steps, you can easily copy data from one website and paste it into a form on another website using JavaScript.
SUMMING UP….
In this article, we have discussed two methods for copying data from one website to another using Python and JavaScript. Both methods provide a quick and efficient way to automate the process of copying data from websites, saving you time and effort. You can use these methods as a starting point and modify them to fit your specific needs and requirements.
