os.fpathconf(fd, name) Return system configuration information relevant to an open file. name specifies the configuration value to retrieve; it may be a string which is the name of a defined system value; these names are specified in a number of standards (POSIX.1, Unix 95, Unix 98, and others). Some platforms define additional names as well. The names known to the host operating system are given in the pathconf_names dictionary. For configuration variables not included in that mapping, pass

class decimal.DefaultContext This context is used by the Context constructor as a prototype for new contexts. Changing a field (such a precision) has the effect of changing the default for new contexts created by the Context constructor. This context is most useful in multi-threaded environments. Changing one of the fields before threads are started has the effect of setting system-wide defaults. Changing the fields after threads have started is not recommended as it would require thread syn

curses.filter() The filter() routine, if used, must be called before initscr() is called. The effect is that, during those calls, LINES is set to 1; the capabilities clear, cup, cud, cud1, cuu1, cuu, vpa are disabled; and the home string is set to the value of cr. The effect is that the cursor is confined to the current line, and so are screen updates. This may be used for enabling character-at-a-time line editing without touching the rest of the screen.

ZipFile.read(name, pwd=None) Return the bytes of the file name in the archive. name is the name of the file in the archive, or a ZipInfo object. The archive must be open for read or append. pwd is the password used for encrypted files and, if specified, it will override the default password set with setpassword(). Calling read() on a closed ZipFile will raise a RuntimeError. Calling read() on a ZipFile that uses a compression method other than ZIP_STORED, ZIP_DEFLATED, ZIP_BZIP2 or ZIP_LZMA

textwrap.indent(text, prefix, predicate=None) Add prefix to the beginning of selected lines in text. Lines are separated by calling text.splitlines(True). By default, prefix is added to all lines that do not consist solely of whitespace (including any line endings). For example: >>> s = 'hello\n\n \nworld' >>> indent(s, ' ') ' hello\n\n \n world' The optional predicate argument can be used to control which lines are indented. For example, it is easy to add prefix to eve

locale.localeconv() Returns the database of the local conventions as a dictionary. This dictionary has the following strings as keys: Category Key Meaning LC_NUMERIC 'decimal_point' Decimal point character. 'grouping' Sequence of numbers specifying which relative positions the 'thousands_sep' is expected. If the sequence is terminated with CHAR_MAX, no further grouping is performed. If the sequence terminates with a 0, the last group size is repeatedly used. 'thousands_sep' Character use

class str(object='') class str(object=b'', encoding='utf-8', errors='strict') Return a str version of object. See str() for details. str is the built-in string class. For general information about strings, see Text Sequence Type — str.

class str(object='') class str(object=b'', encoding='utf-8', errors='strict') Return a string version of object. If object is not provided, returns the empty string. Otherwise, the behavior of str() depends on whether encoding or errors is given, as follows. If neither encoding nor errors is given, str(object) returns object.__str__(), which is the “informal” or nicely printable string representation of object. For string objects, this is the string itself. If object does not have a __str__()

Popen.communicate(input=None, timeout=None) Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for process to terminate. The optional input argument should be data to be sent to the child process, or None, if no data should be sent to the child. The type of input must be bytes or, if universal_newlines was True, a string. communicate() returns a tuple (stdout_data, stderr_data). The data will be bytes or, if universal_newlines was

multiprocessing.get_start_method(allow_none=False) Return the name of start method used for starting processes. If the start method has not been fixed and allow_none is false, then the start method is fixed to the default and the name is returned. If the start method has not been fixed and allow_none is true then None is returned. The return value can be 'fork', 'spawn', 'forkserver' or None. 'fork' is the default on Unix, while 'spawn' is the default on Windows. New in version 3.4.
