搞笑的程序猿:看看你是哪种Python程序员

python scott 237℃ 0评论

本文主要介绍了不同阶段的python程序对同一个问题编写代码的风格,方式的不同比较,比如一年经验的python程序员,懒惰的程序员,python专家,python黑客编写代码风格的不同,从中也可以看看你是属于python程序员里的哪一种:

不久前,在互联网上出现了一篇有趣的文章,讲的是对于同一个问题,不同层次的Python程序员编出的Python代码,显示出了不同的风格,代码都很简单,有趣。下面让我们一起来看看一个Python程序猿进阶的全过程吧。(偷笑)

编程新手

[cc lang=”python”]

def factorial(x):
if x == 0:
return 1
else:
return x * factorial(x – 1) //不简单啊,迭代,新手哦。
print factorial(6)
[/cc]

一年编程经验(学Pascal的)

[cc lang=”python”]

def factorial(x):
result = 1
i = 2
while i <= x: resultresult = result * i ii = i + 1 return result print factorial(6) [/cc]

一年编程经验(学C的)

[cc lang=”python”]

def fact(x): #{
result = i = 1;
while (i <= x): #{ result *= i; i += 1; #} return result; #} print(fact(6)) [/cc]

一年编程经验(读过SICP)

[cc lang=”python”]

@tailcall
def fact(x, acc=1):
if (x > 1):
return (fact((x – 1), (acc * x)))
else:
return acc
print(fact(6))
[/cc]

一年编程经验(Python)

[cc lang=”python”]

def Factorial(x):
res = 1
for i in xrange(2, x + 1):
res *= i
return res
print Factorial(6)
[/cc]

懒惰的Python程序员

[cc lang=”python”]

def fact(x):
return x > 1 and x * fact(x – 1) or 1
print fact(6)
[/cc]

更懒的Python程序员

[cc lang=”python”]

f = lambda x: x and x * f(x – 1) or 1 //匿名函数,厉害。程序猿真是懒人做的!
print f(6)
[/cc]

Python专家

[cc lang=”python”]

fact = lambda x: reduce(int.__mul__, xrange(2, x + 1), 1)
print fact(6) //专家厉害啊。
[/cc]

Python黑客

[cc lang=”python”]

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’) //一般人压根看不懂。
[/cc]

专家级程序员

[cc lang=”python”]

from c_math import fact
print fact(6)
[/cc]

大英帝国程序员

[cc lang=”python”]

from c_maths import fact
print fact(6)
Web设计人员
def factorial(x):
#————————————————-
#— Code snippet from The Math Vault —
#— Calculate factorial (C) Arthur Smith 1999 —
#————————————————-
result = str(1)
i = 1 #Thanks Adam
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) [/cc]

Unix 程序员

[cc lang=”python”]

import os
def fact(x):
os.system(‘factorial ‘ + str(x))
fact(6)
[/cc]

Windows 程序员

[cc lang=”python”]

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) //可能自己都晕菜了... [/cc]

企业级程序员

[cc lang=”python”]

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)) //面向对象,但就此题来说,又长又臭。 [/cc]
