第三题

return reduce(lambda x, y: x + 0.001*y,map(int,s.split('.')))

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

小数点后要不是3位的你这个就是错的，你怎么不直接return 123.456好了

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

0.001换成0.1**len(s.split('.')[1])就好了

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

这个最厉害，一行！

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

我觉得这样还不如直接float(s)呢。。。。。。。
