Python字符串分割

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
