Parse tree is a nodelist. TextNode and ExpressionNode are simple nodes and for-loop, if-loop etc are block nodes, which contain multiple child nodes. Each node can emit some python string. python string emitted by the root node is validated for safeeval and executed using python in the given environment. Enough care is taken to make sure the generated code and the template has line to line match, so that the error messages can point to exact line number in template. (It doesn't work in some cases still.)
