Fibonacci number in a line.
print((lambda n: (lambda f: [f(i, f) for i in range(0, n)]))(10)(lambda n, fib: n if(n == 0 or n == 1) else fib(n - 1, fib) + fib(n - 2, fib)))

Y Combinator Python 版

在 The Y Combinator explained with JavaScript 用 JavaScript 程式碼來解釋何謂 Y Combinator，為了更瞭解 Y Combinator，我自己實作了一個，暫記過程如下 ...

def y(f):
    r = lambda n: f(r)(n)
    return f(r)
    
y(lambda fact: lambda n: 1 if n < 2 else n * fact(n - 1))(3) // 6
