搞笑的程序猿:看看你是哪种Python程序员

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

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)
 

一年编程经验(学Pascal的)

def factorial(x):
  result = 1
  i = 2
  while i <= x:
    resultresult = result * i
    ii = i + 1
  return result
print factorial(6)
 &#91;/code&#93;
<p><strong>一年编程经验(学C的)</strong></p>

def fact(x): #{
  result = i = 1;
  while (i <= x): #{
    result *= i;
    i += 1;
  #}
  return result;
#}
print(fact(6))
 &#91;/code&#93;
<p><strong>一年编程经验(读过SICP)</strong></p>

@tailcall
def fact(x, acc=1):
  if (x > 1):
    return (fact((x - 1), (acc * x)))
  else:
    return acc
print(fact(6))
 

一年编程经验(Python)

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)
 

更懒的Python程序员

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)
 

Python专家

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

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') //一般人压根看不懂。
 

专家级程序员

from c_math import fact
print fact(6)
 

大英帝国程序员

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) #&#63;&#63;&#63;&#63;&#63;&#63;
    result = str(int(result) * i)
    #result = int(str(result) * i)
    i = i + 1
  return result
print factorial(6)
 &#91;/code&#93;
<p><strong>Unix 程序员</strong></p>

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) //可能自己都晕菜了... [/code]

企业级程序员

def new(cls, *args, **kwargs):
return cls(*args, **kwargs)
class Number(object):
pass
class IntegralNumber(int, Number):
def toInt(self):
return new (int, self)

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。 [/code]
