What is the purpose of creating a standalone spider in Scrapy?

• To reduce the size of the project

• To integrate with other spiders

• To run independently as a single Python file

• To enhance the speed of data extraction

Why do we define the base URL and search URL as attributes in the spider class?

• To ensure URLs are hardcoded

• To allow dynamic URL generation

• To make the code more readable

• To prevent URL duplication

How does the spider handle variations in search results?

• By using a different CSS selector

• By adding specific attributes like color edition

• By using a default search term

• By ignoring them

What method is used to find the position of a product in the search results?

• Using the index method

• Using the locate method

• Using the find method

• Using the search method

How does the spider determine if there are more pages to scrape?

• By counting the number of products

• By looking for a 'next' button

• By estimating based on previous searches

• By checking the number of results

What happens if the product is not found on the current page?

• The spider restarts the search

• The spider stops searching

• The spider logs an error

• The spider sends a request to the next page

What is the purpose of exporting data to a JSON file?

• To store the data for future analysis

• To format the data for web display

• To share the data with other applications

• To visualize the data

How is the date formatted before being used as a key in the JSON file?

• Using percent formats for day, month, and year

• Using the default date format

• Using a timestamp

• Using a custom date format

What is the significance of the 'self rank' attribute in the spider?

• It configures the spider's settings

• It determines the speed of the spider

• It stores the rank of the product

• It logs errors encountered during scraping

What is the final step after setting up the spider and exporting data?

• Running the spider to test it

• Deleting temporary files

• Optimizing the spider's performance

• Sharing the results with stakeholders
