Python程序员的进化史

几年前在网上流行一段很有趣的代码,今日有缘得见,捧腹一笑。

#新手程序员
def factorial(x): if x == 0: return 1 else: return x * factorial(x - 1) print factorial(6)
#有一年 Pascal 经验的程序员
def factorial(x): result = 1 i = 2 while i <= x: result = result * i i = i + 1 return result print factorial(6)
#有一年 C 经验的程序员
def fact(x): #{ result = i = 1; while (i <= x): #{ result *= i; i += 1; #} return result; #} print(fact(6))
#有一年 SICP 经验的程序员
@tailcall def fact(x, acc=1): if (x > 1): return (fact((x - 1), (acc * x))) else: return acc print(fact(6))
#有一年 Python 经验的程序员
def Factorial(x): res = 1 for i in xrange(2, x + 1): res *= i return res print Factorial(6)
#懒惰的Python程序员
def fact(x): return x > 1 and x * fact(x - 1) or 1 print fact(6)
#更懒惰的Python程序员
f = lambda x: x and x * f(x - 1) or 1 print f(6)
#专家级Python程序员
import operator as op import functional as f fact = lambda x: f.foldl(op.mul, 1, xrange(2, x + 1)) print fact(6)
#Python 黑客
import sys @tailcall def fact(x, acc=1): if x: return fact(x.__sub__(1), acc.__mul__(x)) return acc sys.stdout.write(str(fact(6)) + '\n')
#专家级程序员
import c_math fact = c_math.fact print fact(6)
#英国专家级程序员 (译注:在英式英语中,“数学”的简写,多用“maths”,不是“math"。)
import c_maths fact = c_maths.fact print fact(6)
#网页设计师
def factorial(x): #------------------------------------------------- #--- 这段代码是从 Math Vault 那弄过来滴--- #--- 计算阶乘 (C)亚瑟·史密斯 1999年--- #------------------------------------------------- result = str(1) i = 1 #谢谢亚当 while i <= x: #result = result * i #It's faster to use *= #result = str(result * result + i) #result = int(result *= i) #?????? result str(int(result) * i) #result = int(str(result) * i) i = i + 1 return result print factorial(6)
#Unix 程序员
import os def fact(x): os.system('factorial ' + str(x)) fact(6)
#Windows 程序员
NULL = None def CalculateAndPrintFactorialEx(dwNumber, hOutputDevice, lpLparam, lpWparam, lpsscSecurity, *dwReserved): if lpsscSecurity != NULL: return NULL #Not implemented dwResult = dwCounter = 1 while dwCounter <= dwNumber: dwResult *= dwCounter dwCounter += 1 hOutputDevice.write(str(dwResult)) hOutputDevice.write('\n') return 1 import sys CalculateAndPrintFactorialEx(6, sys.stdout, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL)
#企业程序员
def new(cls, *args, **kwargs): return cls(*args, **kwargs) class Number(object): pass class IntegralNumber(int, Number): def toInt(self): return new (int, self) class InternalBase(object): def __init__(self, base): self.base = base.toInt() def getBase(self): return new (IntegralNumber, self.base) class MathematicsSystem(object): def __init__(self, ibase): Abstract @classmethod def getInstance(cls, ibase): try: cls.__instance except AttributeError: cls.__instance = new (cls, ibase) return cls.__instance class StandardMathematicsSystem(MathematicsSystem): def __init__(self, ibase): if ibase.getBase() != new (IntegralNumber, 2): raise NotImplementedError self.base = ibase.getBase() def calculateFactorial(self, target): result = new (IntegralNumber, 1) i = new (IntegralNumber, 2) while i <= target: result = result * i i = i + new (IntegralNumber, 1) return result print StandardMathematicsSystem.getInstance(new (InternalBase, new (IntegralNumber, 2))).calculateFactorial(new (IntegralNumber, 6))
