Type Hints · interview question
Which move is the best default when protocols becomes part of this workflow?
Multiple choiceMediumchapter-10-curatedpremiumtype-hintsprotocols
Answer and explanation
Correct answer
B. Use protocols when the code depends on a capability or method set rather than on one specific implementation.
Why
Use protocols when the code depends on a capability or method set rather than on one specific implementation. That is the stronger engineering move because this is an interview-friendly topic because it shows you understand behavior-driven design in python. Over-coupling to one concrete class makes testing and substitution harder than necessary.
