Scripting in Python

Scripting in Python

The Jython interpreter is used by screen-scraper to allow for scripting in Python. Jython is a very fast interpreter, and we'd recommend using it if you're familiar with the Python programming language.

When scripting in Python all of the standard Java classes can be used. Classes must be imported using a special directive, which is also required if you'd like to create one of screen-scraper's RunnableScrapingSession objects. Here's an example that will run the "Weather" scraping session (which is found in the default screen-scraper installation):

# Import the RunnableScrapingSession class.
from com.screenscraper.scraper import RunnableScrapingSession

# Generate a new "Weather" scraping session.
runnableScrapingSession = RunnableScrapingSession( "Weather" )

# Put the zip code in a session variable so we can reference it later.
runnableScrapingSession.setVariable( "ZIP_CODE", "90001" )

# Tell the scraping session to scrape.
runnableScrapingSession.scrape()

Notice that before the RunnableScrapingSession class can be used it first must be imported.
