1. Web scraping is the process of extracting data from web pages using code. It can be useful when the data is not available in a structured format such as a table or a file.
2. There are many tools and libraries that can help you with web scraping, such as BeautifulSoup, Scrapy, and Selenium in Python. You can also use browser extensions such as Web Scraper and Data Miner.
1. Lambda Functions
Lambda functions are particularly useful in cases where we need to have a short one-time use function.
Syntax: lambda arguments: expression
2. Exceptional Handling
An exception is a condition that occurs during the execution of the program and interrupts the execution.
We use to try and except blocks to handle exceptions in python. To handle multiple exceptions at a time we use multiple except blocks.
What is data science and why now is the time to start building your skills?
