related via subclassing are never equivalent, even if they have the same name. The built-in exceptions listed below can be generated by the interpreter or built-in python valueerror example functions. Except where mentioned, they have an "associated value" indicating the detailed cause of the error. This may be a string or a tuple of several items of information (e.g., an error code and a string explaining the code). The associated value is usually passed as arguments to the exception class's constructor. python 3 exceptions User code can raise built-in exceptions. This can be used to test an exception handler or to report an error condition "just like" the situation in which the interpreter raises the same exception; but beware that there is nothing to prevent user code from raising an inappropriate error. The built-in exception classes can be subclassed to define new exceptions; programmers are encouraged to derive new exceptions from the Exception class or one of its subclasses, and not from BaseException. More information on defining exceptions is available in the Python Tutorial under User-defined Exceptions. When raising (or re-raising) an exception in an except or finally clause __context__ is automatically set to the last exception caught; if the new exception is not handled the traceback that is eventually displayed will include the originating exception(s) and the final exception. When raising a new exception (rather than using a bare raise Lib/configparser.py This module provides the ConfigParser class which implements a basic configuration language which provides a structure similar to what's found in Microsoft Windows INI python errno files. You can use this to write Python programs which can be customized by end users easily. Note This library does not interpret or write the value-type prefixes used in the Windows Registry extended version of INI syntax. See https://docs.python.org/3/library/exceptions.html also Module shlex Support for a creating Unix shell-like mini-languages which can be used as an alternate format for application configuration files. Module json The json module implements a subset of JavaScript syntax which can also be used for this purpose. 14.2.1. Quick Start¶ Let's take https://docs.python.org/3/library/configparser.html a very basic configuration file that looks like this: [DEFAULT] ServerAliveInterval = 45 Compression = yes CompressionLevel = 9 ForwardX11 = yes [bitbucket.org] User = hg [topsecret.server.com] Port = 50022 ForwardX11 = no The structure of INI files is described in the following section. Essentially, the file consists of sections, each of which contains keys with values. configparser classes can read and write such files. Let's start by creating the above configuration file programmatically. >>> import configparser >>> config = configparser.ConfigParser() >>> config['DEFAULT'] = {'ServerAliveInterval': '45', ... 'Compression': 'yes', ... 'CompressionLevel': '9'} >>> config['bitbucket.org'] = {} >>> config['bitbucket.org']['User'] = 'hg' >>> config['topsecret.server.com'] = {} >>> topsecret = config['topsecret.server.com'] >>> topsecret['Port'] = '50022' # mutates the parser >>> topsecret['ForwardX11'] = 'no' # same here >>> config['DEFAULT']['ForwardX11'] = 'yes' >>> with open('example.ini', 'w') as configfile: ... config.write(configfile) ...

What is config? I'm guessing 'fp' is a file pointer. Maybe you forgot to open the file, or you did but id failed for some reason? –Yotam Jul 14 '13 at 10:13 I have updated it so I hope that gives you an idea –Arctomium Jul 14 '13 at 10:17 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted As the documentation says: write(fileobject, space_around_delimiters=True) Write a representation of the configuration to the specified file object, which must be opened in text mode (accepting strings). So you problem is, you are missing the file-object argument from the write method: config = configparser.ConfigParser() # do some configuration here with open('settings.ini', 'w') as settings: config.write(settings) # write to a file share|improve this answer edited Jul 14 '13 at 10:49 answered Jul 14 '13 at 10:42 Peter Varo 5,31712344 add a comment| Your Answer draft s Format Reading Configuration Files Unicode Configuration Data Accessing Configuration Settings Testing whether values are present Value Types Options as Flags Modifying Settings Saving Configuration Files Option Search Path Combining Values with Interpolation Using Defaults Substitution Errors Navigation Table of Contents Previous: csv - Comma-separated value files Next: robotparser - Internet spider access control This Page Show Source Examples The output from all the example programs from PyMOTW has been generated with Python 2.7.8, unless otherwise noted.

Navigation index modules | next | previous | PyMOTW » File Formats » ConfigParser - Work with configuration files¶ Purpose:Read/write configuration files similar to Windows INI files Available In:1.5 Use the ConfigParser module to manage user-editable configuration files for an application. The configuration files are organized into sections, and each section can contain name-value pairs for configuration data. Value interpolation using Python formatting strings is also supported, to build values that depend on one another (this is especially handy for URLs and message strings). Configuration File Format¶ The file format used by ConfigParser is similar to the format used by older versions of Microsoft Windows. It consists of one or more named sections, each of which can contain individual options with names and values. Config file sections are identified by looking for lines starting with [ and ending with ]. The value between the square brackets is the section name, and can contain any characters except square brackets. Options are listed one per line within a section. The line starts with the name of the option, which is separated from the value by a colon (:) or equal sign (=). Whitespace around the separator is ignored when the file is parsed.
