« Originally, Python was dynamically scoped. This basically means that, to evaluate an expression, a compiler first searches the current block and then successively all the calling functions. » Python was never dynamically scoped. Before Python 2.2 it had a three-level static scoping system, and nested functions didn't have any access to variables from their parent function's scope.
