• How should I write this string-prefix check so that it's idiomatic Python?

  - by Kevin Stargel

  I have a couple of lists of items: specials = ['apple', 'banana', 'cherry', ...] smoothies = ['banana-apple', 'mocha mango', ...] I want to make a new list, special_smoothies, consisting of elements in smoothies that start with the elements in specials. However, if specials is blank, special_smoothies should be identical to smoothies. What's the most Pythonic way to do this? Is there a way to do this without a separate conditional check on whether specials is blank?

• How to check if location services are enabled for a particular app prior to iOS 4.2?

  - by NobleK

  Hello How can I check if the user has allowed location for mu app? Normally I would use authorizationStatus method of the CLLocationManager class, but it is only available in iOS 4.2 and newer. Is it possible to achieve this somehow while still using SDK 4.2, so that the app can still run on devices with older versions of iOS, or do I have to downgrade the SDK? And along the same line, I need a similar alternative for the locationServicesEnabled method prior to iOS 4.0. Thanx
