response.read() returns an instance of bytes while StringIO is an in-memory stream for text only. Use BytesIO instead. From What’s new in Python 3.0 – Text Vs. Data Instead Of Unicode Vs. 8-bit The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.
You need to seek to the beginning of compressedFile after writing to it but before passing it to gzip.GzipFile(). Otherwise it will be read from the end by gzip module and will appear as an empty file to it. See below: #! /usr/bin/env python import urllib2 import StringIO import gzip baseURL = “https://www.kernel.org/pub/linux/docs/man-pages/” filename = … Read more
For Python 2.x, use the StringIO module. For example: >>> from cStringIO import StringIO >>> f = StringIO(‘foo’) >>> f.read() ‘foo’ I use cStringIO (which is faster), but note that it doesn’t accept Unicode strings that cannot be encoded as plain ASCII strings. (You can switch to StringIO by changing “from cStringIO” to “from StringIO”.) … Read more
Pandas expects a filename path to the ExcelWriter constructors although each of the writer engines support StringIO. Perhaps that should be raised as a bug/feature request in Pandas. In the meantime here is a workaround example using the Pandas xlsxwriter engine: import pandas as pd import StringIO io = StringIO.StringIO() # Use a temp filename … Read more
TL;DR Don’t bother clearing it, just create a new one—it’s faster. The method Python 2 Here’s how I would find such things out: >>> from StringIO import StringIO >>> dir(StringIO) [‘__doc__’, ‘__init__’, ‘__iter__’, ‘__module__’, ‘close’, ‘flush’, ‘getvalue’, ‘isatty’, ‘next’, ‘read’, ‘readline’, ‘readlines’, ‘seek’, ‘tell’, ‘truncate’, ‘write’, ‘writelines’] >>> help(StringIO.truncate) Help on method truncate in module … Read more
extractall extracts to the file system, so you won’t get what you want. To extract a file in memory, use the ZipFile.read() method. If you really need the full content in memory, you could do something like: def extract_zip(input_zip): input_zip=ZipFile(input_zip) return {name: input_zip.read(name) for name in input_zip.namelist()}
From Python 3.0 changelog: The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively. From the Python 3 email documentation it can be seen that io.StringIO should be used instead: from io import StringIO from email.generator import Generator fp = StringIO() g = … Read more
If you have Python version >= 2.7, you can use subprocess.check_output which basically does exactly what you want (it returns standard output as string). Simple example (linux version, see note): import subprocess print subprocess.check_output([“ping”, “-c”, “1”, “8.8.8.8”]) Note that the ping command is using linux notation (-c for count). If you try this on Windows … Read more
