python函数式编程

直接上代码，类似与swift

#! /usr/bin/env python

#def add(x,y,f):#    return f(x)+f(y);#print (add(-5,-10,abs));#def format_name(s):#    return s[0].upper() + s[1:].lower();#print map(format_name,['adam', 'LISA', 'barT'])#def prod(x, y):#    return x*y#print reduce(prod, [2, 3,4, 5],10)#import math#def is_sqr(x):#    r = int(math.sqrt(x))#    return r*r==x#print filter(is_sqr, range(1, 101))def is_not_empty(s):    return s and len(s.strip()) > 0print filter(is_not_empty, ['test', None, '', 'str', '  ', 'END'])
