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)
一年编程经验(学C的)
def fact(x): #{
result = i = 1;
while (i <= x): #{
result *= i;
i += 1;
#}
return result;
#}
print(fact(6))
一年编程经验(读过SICP)
@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) #??????
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) //可能自己都晕菜了...
