這篇文章主要介紹了搞笑的程序猿：看看你是哪種Python程序員,不久前,在互聯(lián)網(wǎng)上出現(xiàn)了一篇有趣的文章,講的是對于同一個問題,不同層次的Python程序員編出的Python代碼，顯示出了不同的風(fēng)格,代碼都很簡單,有趣,需要的朋友可以參考下

不久前，在互聯(lián)網(wǎng)上出現(xiàn)了一篇有趣的文章，講的是對于同一個問題，不同層次的Python程序員編出的Python代碼，顯示出了不同的風(fēng)格，代碼都很簡單，有趣。下面讓我們一起來看看一個Python程序猿進(jìn)階的全過程吧。(偷笑)

編程新手

def factorial(x):  
  if x == 0:  
    return 1  
  else:  
    return x * factorial(x - 1) //不簡單啊，迭代，新手哦。 
print factorial(6)

一年編程經(jīng)驗(學(xué)Pascal的)

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

一年編程經(jīng)驗(學(xué)C的)

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

一年編程經(jīng)驗(讀過SICP)

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

一年編程經(jīng)驗(Python)

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

懶惰的Python程序員

def fact(x):  
  return x > 1 and x * fact(x - 1) or 1  
print fact(6)

更懶的Python程序員

f = lambda x: x and x * f(x - 1) or 1 //匿名函數(shù)，厲害。程序猿真是懶人做的！ 
print f(6)

Python專家

fact = lambda x: reduce(int.__mul__, xrange(2, x + 1), 1)  
print fact(6)               //專家厲害啊。

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') //一般人壓根看不懂。

專家級程序員

from c_math import fact  
print fact(6)

大英帝國程序員

Web設(shè)計人員
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)

Unix 程序員

import os  
def fact(x):  
  os.system('factorial ' + str(x))  
fact(6)

Windows 程序員

                 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

 NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL) //可能自己都暈菜了...
