fold(name, value) Headers are folded using the Header folding algorithm, which preserves existing line breaks in the value, and wraps each resulting line to the max_line_length. Non-ASCII binary data are CTE encoded using the unknown-8bit charset.

email.utils.localtime(dt=None) Return local time as an aware datetime object. If called without arguments, return current time. Otherwise dt argument should be a datetime instance, and it is converted to the local time zone according to the system time zone database. If dt is naive (that is, dt.tzinfo is None), it is assumed to be in local time. In this case, a positive or zero value for isdst causes localtime to presume initially that summer time (for example, Daylight Saving Time) is or is

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.

winreg.DeleteKey(key, sub_key) Deletes the specified key. key is an already open key, or one of the predefined HKEY_* constants. sub_key is a string that must be a subkey of the key identified by the key parameter. This value must not be None, and the key may not have subkeys. This method can not delete keys with subkeys. If the method succeeds, the entire key, including all of its values, is removed. If the method fails, an OSError exception is raised. Changed in version 3.3: See above.

bz2.open(filename, mode='r', compresslevel=9, encoding=None, errors=None, newline=None) Open a bzip2-compressed file in binary or text mode, returning a file object. As with the constructor for BZ2File, the filename argument can be an actual filename (a str or bytes object), or an existing file object to read from or write to. The mode argument can be any of 'r', 'rb', 'w', 'wb', 'x', 'xb', 'a' or 'ab' for binary mode, or 'rt', 'wt', 'xt', or 'at' for text mode. The default is 'rb'. The comp

recv(buffer_size) Read at most buffer_size bytes from the socket’s remote end-point. An empty bytes object implies that the channel has been closed from the other end. Note that recv() may raise BlockingIOError , even though select.select() or select.poll() has reported the socket ready for reading.

log_date_time_string() Returns the current date and time, formatted for logging.

multiprocessing.freeze_support() Add support for when a program which uses multiprocessing has been frozen to produce a Windows executable. (Has been tested with py2exe, PyInstaller and cx_Freeze.) One needs to call this function straight after the if __name__ == '__main__' line of the main module. For example: from multiprocessing import Process, freeze_support def f(): print('hello world!') if __name__ == '__main__': freeze_support() Process(target=f).start() If the freeze_s

exception configparser.InterpolationError Base class for exceptions raised when problems occur performing string interpolation.

turtle.undobufferentries() Return number of entries in the undobuffer. >>> while undobufferentries(): ... undo()
