David and Randy share some of their thoughts on functions, methods, and multiple dispatch in Julia from the perspective as new users coming to Julia from Python.

Learn how Julia's type declarations and multiple dispatch system allow you to redefine functions with different behavior depending on the types of their arguments and explore some of the differences between functions in Julia and functions in Python.
