summary

Covers concrete implementations rather than theory: untyped lambda calculus encoded with Python lambda showing how to implement abstraction and application, substitution, and basic combinators; encodes datatypes — Church numerals, booleans and logical ops — and implements successor/add/mul, predecessor and predicates; demonstrates recursion via the Y combinator and shows factorial(6)=720 and fibonacci(9)=34 while explaining Python s eager evaluation implications and the practical workarounds used.
