There has been a problem that has been bugging me for a while for
reading input from standard in. Consider the following simple program:
#!/usr/bin/env python
import sys
print 'enter something: ',
answer = sys.stdin.readline().strip()
print 'you answered {%s}' % (answer)
When I run this interactively, the following happens:
$ ~/tmp/foo.py
enter something: hi
you answered {hi}
Notice the extra space before 'you'; I did not put it there. It seems
that this problem can be avoided if I instead use the program:
#!/usr/bin/env python
import code
answer = code.InteractiveConsole().raw_input('enter something: ')
print 'you answered {%s}' % (answer)
Now, the output is:
$ ~/tmp/foo.py
enter something: hi
you answered {hi}
Is this a well-known problem? Is it a bug? I do not see why that
extra space is getting there in the first version. Using the code
module seems a little dirty, when sys.stdin is available. This is
python 2.4 on a Linux platform. Thank you,
