Which move is the best default when functools.wraps becomes part of this workflow?
Multiple choiceEasychapter-14-curatedpremiumadvanced-pythonfunctools-wraps
Answer and explanation
Correct answer
B. Use wraps so the decorated function still behaves like itself for debugging, docs, and introspection.
Why
Use wraps so the decorated function still behaves like itself for debugging, docs, and introspection. That is the stronger engineering move because candidates sound more experienced when they mention why wraps exists rather than only that it should be added. Skipping wraps can make stack traces and framework behavior harder to interpret.
