#1 Created at ... [Delete] [Delete and Lock User]

def normalize(name):

return name.capitalize()

#2 Created at ... [Delete] [Delete and Lock User]

没有用到map，是不是不对啊？

#3 Created at ... [Delete] [Delete and Lock User]

还有这样的，只是做了字符串分解，也没有用到map啊

def normalize(name):

name=name[0].upper()+name[1:].lower()

return name

#4 Created at ... [Delete] [Delete and Lock User]

DIGITS = {'0': 0, '1': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8, '9': 9}

def char2num(l):

return DIGITS[l]

return reduce(lambda x,y:x*10+y,map(char2num,s.split('.')[0])) + (reduce(lambda x,y:(x*10+y),map(char2num,s.split('.')[1])))/1000

#5 Created at ... [Delete] [Delete and Lock User]

map函数已经在print L2时用到了，注意联系上下文。。。
