Writing C extension code that consumes data from any Python file-like object (e.g., normal files, StringIO objects, etc.). read() method has to be repeatedly invoke
The workhorse function for reading text files (a.k.a. flat files) is read_csv() . See the cookbook for New in version 0.18.1: support for the Python parser. In [1]: from io import StringIO, BytesIO In [2]: data = ('col1,col2,col3\n': 'a,b,1\n' CSV file: df = pd.read_csv('https://download.bls.gov/pub/time.series/cu/cu.item', sep='\t'). import pycurl from StringIO import StringIO buffer = StringIO() c = pycurl. In Python 3, PycURL returns the response body as a byte string. This is handy if we are downloading a binary file, but for text documents we must decode the byte string. Getting data into and out of files in Python feels a lot like using the low-level methods a newly created string object with the full contents of the StringIO buffer. local_path is the local file path where the downloaded file or files will be stored. It may be interpolated, using standard Python dict-based interpolation, with the If a file-like object such as StringIO has a name attribute, that will be used in This document explains how to output CSV (Comma Separated Values) dynamically using Django views. To do this, you can either use the Python CSV library
Example of use: In Python, parse an article file written in EML into a tree of Python objects, and search down through the tree in order to extract the title and the author name from the relevant elements. It is distributed as a single, statically linked 32-bit Linux executable binary, which contains the Python scripting engine, the interactive interpreter with command editing (readline), the Python debugger (pdb), most standard Python… Python from novice to pro File Tools The File Object Model in Python 3.X Using Built-in File Objects Binary and Text Files Lower-Level File Tools in the os Module File Scanners Directory Tools Walking One Directory Walking Directory Trees Handling Unicode Filenames… Rapid GUI Programming with Python and Qt Prentice Hall Open Source Software Development Series Arnold Robbins, Series Nginx, pronounced "engine X", is a fast and lightweight web server, that can be used to serve static files, but is often used as a reverse proxy. It has some very nice features like load balancing and rate limiting.
The StringIO and cStringIO Modules You can implement file-like objects by writing Python classes that supply the methods you need. If all you want is for data to Odoo11: Python 3 expects string, not bytes, when writing to file-like objects. 2/2/18, 12:26 I did changed import StringIO from io, but no luck.

StringIO() stream_data = report_downloader.DownloadReportAsStream( This module contains additional types of stream (file-like) objects and helper functions. So, while MicroPython doesn't support buffered streams, it still provides for Initial contents of file-like objects can be specified with string parameter (should be normal string for StringIO or bytes object for BytesIO ).
