Re: StringIO.readline() returns ''

You can also just type buf.getvalue() which returns the current
StringIO buffer as a python string, without the rewinding

StringIO.readline() returns ''

[Max]

I'm using StringIO for the first time (to buffer messages recieved from 
a socket). I thought it would be a simple matter of writing the stuff to
the buffer and then calling readline, but that doesn't seem to work:

  buf = StringIO.StringIO()
  buf.write(Foo\n)
  buf.write(Bar\n)
  buf.flush()
  buf.readline()
''

I expected buf.readline() to return 'Foo\n'. What am I doing wrong?

you forgot to rewind the file:

 buf = StringIO.StringIO()
 buf.write(Foo\n)
 buf.write(Bar\n)
 buf.seek(0)
 buf.readline()
'Foo\n'
