Question:
How do I get a byte stream that works like StringIO for Python 2.5?
Application:
I'm converting a PDF to text, but don't want to save a file to the hard disk.
Other Thoughts:
I figured I could use StringIO, but there's no mode parameter (I guess "String" implies text mode).
Apparently the io.BytesIO class is new in v2.6,...
I need to loop until I hit the end of a file-like object, but I'm not finding an "obvious way to do it", which makes me suspect I'm overlooking something, well, obvious. :-)
I have a stream (in this case, it's a StringIO object, but I'm curious about the general case as well) which stores an unknown number of records in "<length><data>...
I'm getting a
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 34: ordinal not in range(128)
on a string stored in 'a.desc' below as it contains the '£' character. It's stored in the underlying Google App Engine datastore as a unicode string so that's fine. The cStringIO.StringIO.writelines function is t...
How can I get the output of a process run using subprocess.call()?
Passing a StringIO.StringIO object to stdout gives this error:

I am avoiding the creation of files on disk, this is what I have got so far:
def get_zip(request):
import zipfile, StringIO
i = open('picture.jpg', 'rb').read()
o = StringIO.StringIO()
zf = zipfile.ZipFile(o, mode='w')
zf.writestr('picture.jpg', i)
zf.close()
o.seek(0)
response = HttpResponse(o.read())

What is the best way to write the contents of a StringIO buf to a file ?
I currently do something like:
buf = StringIO()
fd = open ('file.xml', 'w')
# populate buf
fd.write (buf.getvalue ())
But then all of buf would be loaded in memory at the same time.. ?

Hi,
The code is in python.
Please find below the piece of code that I use to tokenize a string.
strList = list(token[STRING] for token in generate_tokens(StringIO(line).readline) if token[STRING])
I get an error that reads like:-
raise TokenError, ("EOF in multi-line statement", (lnum, 0))
tokenize.TokenError: ('EOF in multi-li...
Hello,
I have this code which runs fine in Python 2.5 but not in 2.7:
import sys
import traceback
try:
from io import StringIO
except:
from StringIO import StringIO
def CaptureExec(stmt):
oldio = (sys.stdin, sys.stdout, sys.stderr)
sio = StringIO()
sys.stdout = sys.stderr = sio
try:
exec(stmt, globals()...
I am using an io.StringIO object to mock a file in a unit-test for a class. The problem is that this class seems expect all strings to be unicode by default, but the builtin str does not return unicode strings:
>>> buffer = io.StringIO()
>>> buffer.write(str((1, 2)))
TypeError: can't write str to text stream
But
>>> buffer.write(str(...
I want to create an array.array object from a cStringIO object:
import cStringIO, array
s = """
<several lines of text>
"""
f = cStringIO.StringIO(s)
a = array.array('c')
a.fromfile(f, len(s))
But I get the following exception:
Traceback (most recent call last):
File "./myfile.py", line 22, in <modu...
Hi,
Is there something equivalent to Python's StingIO for Clojure?
I'm trying to write a report generating/literate programming system similar to Sweave and Pweave for Clojure. I'm currently using a temp file, but I'd prefer using something similar to StringIO.

Hello everybody! I came up with the following problem: CODE A works right now.. I am saving a png file called chart.png locally, and then I am loading it into the proprietary function (which I do not have access).
However, in CODE B, am trying to use cStringIO.StringIO() so that I do not have to write the file "chart.png" to the disk. ...
