How to assign a specific value to sys.stdin?

I'm using the following code:

#!/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

When i run the above code, the print line prints out each character of the texts assigned to sys.stdin. It prints one character per line:

h
e
l
l
o

I

....truncated

I'm trying to get the output to be as it was stored in sys.stdin, it should look like this:

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

  • This seems to work:

    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()

    Output:

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