Using regexps (regular expressions) in your app.yaml url handlers allows you more control over your URLs and how you structure your app. You can also use regexps in your WSGI handlers within your Python code, either instead of or in addition to the app.yaml patterns, for more control.
In the example you quoted, they are choosing a Python handler script based on the URL. If the request was for "/profile/jim/smith", then the app.yaml would cause GAE to route the request to a handler in "/ employee/smith/jim.py" (\1 matches the first paren block "jim", \2 the second "smith", etc.). Another example: - url: /cars-by-year-month/(\d+)/(\d+) script: /\1/cars.py That would route "/cars-by-year-month/2007/11" to the script "/2007/ cars.py", which could then further apply regexps to analyze the month requested, etc. Each year you would add a new folder (2008, 2009, ...) with a "cars.py" and all information about cars that year.
