上海黄浦区Python培训哪家专业

新手程序员

def factorial(x):    if x == 0:        return 1    else:        return x * factorial(x - 1) print factorial(6)

一年经验程序员，使用Pascal

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

一年经验程序员，使用C

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

一年经验程序员，使用SICP

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

一年经验程序员，使用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 print f(6)

Python行家程序员

import operator as op import functional as f fact = lambda x: f.foldl(op.mul, 1, xrange(2, x + 1)) print fact(6)

Python hacker

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')

行家程序员

import c_math fact = c_math.fact print fact(6)

英文行家程序员

import c_maths fact = c_maths.fact print fact(6)
