如何为sys.stdin分配特定值？

我正在使用以下代码：

#!/usr/bin/env python

import sys
from io import StringIO

#data = sys.stdin.readlines()
sys.stdin = """
hello I feel good
how are you?
where have you been?
"""
for line in sys.stdin:
    print line

当我运行上述代码时,打印行将打印出分配给sys.stdin的文本的每个字符.每行打印一个字符：

h
e
l
l
o

I

....truncated

我正在尝试将输出保存在sys.stdin中,它应如下所示：

hello I feel good
how are you?
where have you been?

from io import StringIO
import sys

data = u"""
hello I feel good
how are you?
where have you been?
"""

sys.stdin = StringIO(data)

for line in sys.stdin:
    print line.rstrip()

输出：

hello I feel good
how are you?
where have you been?
