mimetypes.types_map Dictionary mapping filename extensions to MIME types.

ctypes.util.find_msvcrt() Windows only: return the filename of the VC runtime library used by Python, and by the extension modules. If the name of the library cannot be determined, None is returned. If you need to free memory, for example, allocated by an extension module with a call to the free(void *), it is important that you use the function in the same library that allocated the memory.

turtle.resetscreen() Reset all Turtles on the Screen to their initial state. Note This TurtleScreen method is available as a global function only under the name resetscreen. The global function reset is another one derived from the Turtle method reset.

doctest.debug_src(src, pm=False, globs=None) Debug the doctests in a string. This is like function debug() above, except that a string containing doctest examples is specified directly, via the src argument. Optional argument pm has the same meaning as in function debug() above. Optional argument globs gives a dictionary to use as both local and global execution context. If not specified, or None, an empty dictionary is used. If specified, a shallow copy of the dictionary is used.

discard(key) Delete the message corresponding to key from the mailbox. If no such message exists, a KeyError exception is raised if the method was called as remove() or __delitem__() but no exception is raised if the method was called as discard(). The behavior of discard() may be preferred if the underlying mailbox format supports concurrent modification by other processes.

locale.resetlocale(category=LC_ALL) Sets the locale for category to the default setting. The default setting is determined by calling getdefaultlocale(). category defaults to LC_ALL.

exception EOFError Raised when the input() function hits an end-of-file condition (EOF) without reading any data. (N.B.: the io.IOBase.read() and io.IOBase.readline() methods return an empty string when they hit EOF.)

is_nan(x) Returns True if x is a qNaN or sNaN; otherwise returns False.

popitem() Return an arbitrary (key, message) pair, where key is a key and message is a message representation, and delete the corresponding message. If the mailbox is empty, raise a KeyError exception. The message is represented as an instance of the appropriate format-specific Message subclass unless a custom message factory was specified when the Mailbox instance was initialized.

set_seq2(b) Set the second sequence to be compared. The first sequence to be compared is not changed.
