Functional Abstraction which a ? 1 2 3 4 5 6 a = 1 def f(g): a = 2 return lambda y: a * g(y) # a is 2 f(lambda y: a + y)(a) # a is 1 Return 求反函数整数点的解法，有意思记录一下 Abstraction 在python里面函数的内在名称(intrinsic name)用于用户识别而已

Sound what the HoF usage? 🤔 make a song! 省流：写了一个马里奥的song，感觉和61B后期的一个lab很相似（61 B的电音一点hhh） 😏

Environments Nested Environments in Python 注意环境追溯的顺序，从内到外 Lambda Functions 函数式编程的核心思想是抽象和函数式编程，lambda函数是一种匿名函数，可以把函数作为参数传递给其他函数，或者作为返回值返回 1 2 3 f = lambda x: x + 1 print(f(1)) # Output: 2 print((lambda x: x + 8)(1)) 和def函数的区别 Function Currying Currying: transforming a multi-argument function into a single-argument, higher-order function. 1 2 3 4 5 6 7 8 9 10 def curry2(f): def g(x): def h(y): return f(x, y) return h return g # Another example curry2b = lambda f: (lambda x: (lambda y: f(x, y)))
