Modifying numeric values scraped from website

Python Help
1

Hello,

I am building a simple webscraper to take information from a website and modify said information.

In this situation, I am scraping a recipe and taking the ingredients. One of said ingredients is:
“3 ½ to 4 pound beef chuck roast”

However, I cannot get python to recognize that 3 ½ is equal to 3 1/2 or 3.5

What code can be used to make it understand?
