What will be the result of running the code that asserts the user has 'admin' in the list, given ['user']?

• A. Program outputs 'You are granted full access to the application.'
• B. AssertionError: No admin found
• C. TypeError
• D. ValueError

Answer: (B)

The idea here is how an assert statement behaves when its condition is false. An assertion checks a condition and raises an AssertionError if that condition isn’t met. The code is asserting that the string 'admin' is in the list. But the list provided is ['user'], which does not contain 'admin', so the condition fails. Because of that, an AssertionError is raised, and if a message was supplied in the assertion (as "No admin found"), that message accompanies the error, yielding: AssertionError: No admin found. This shows how assertions enforce expected state during execution. In normal runs you’ll see this error; in optimized runs (with certain Python flags) assertions can be skipped, but that’s a separate behavior.
