代码如下：
[root@localhost test]# cat 3.py
#coding=utf-8
ev = """ 1evilxr 2www 3nihao 4evilxr.com
5dkfjls 6cnblog 7ldskf 8guess 9right """
print ev #打印ev
ev1 = ev.replace('\n','').strip() #去掉ev首尾的空格
print ev1
a = ev1.find(" ") #寻找第一个空格的位置
w1 = ev1[:a] #利用切片切出第一个部分
print w1
b = a
while b <= len(ev1) and b != -1 :#如果不限制b不为-1的话，就会是死循环
while ev1[a] == " ":
a = a + 1
b = ev1.find(" ",a)
if b == -1:
print ev1[a:]
else:
print ev1[a:b]
a = b
运行结果：
[root@localhost test]# python 3.py
