tracemalloc.is_tracing() True if the tracemalloc module is tracing Python memory allocations, False otherwise. See also start() and stop() functions.

copy_abs(x) Returns a copy of x with the sign set to 0.

output_charset Some character sets must be converted before they can be used in email headers or bodies. If the input_charset is one of them, this attribute will contain the name of the character set output will be converted to. Otherwise, it will be None.

locale.getpreferredencoding(do_setlocale=True) Return the encoding used for text data, according to user preferences. User preferences are expressed differently on different systems, and might not be available programmatically on some systems, so this function only returns a guess. On some systems, it is necessary to invoke setlocale() to obtain the user preferences, so this function is not thread-safe. If invoking setlocale is not necessary or desired, do_setlocale should be set to False.

date.__format__(format) Same as date.strftime(). This makes it possible to specify a format string for a date object when using str.format(). For a complete list of formatting directives, see strftime() and strptime() Behavior.

set_exception(exception) Sets the result of the work associated with the Future to the Exception exception. This method should only be used by Executor implementations and unit tests.

exception py_compile.PyCompileError Exception raised when an error occurs while attempting to compile the file.

class typing.ItemsView(MappingView, Generic[KT_co, VT_co]) A generic version of collections.abc.ItemsView.

inspect.getdoc(object) Get the documentation string for an object, cleaned up with cleandoc(). If the documentation string for an object is not provided and the object is a class, a method, a property or a descriptor, retrieve the documentation string from the inheritance hierarchy. Changed in version 3.5: Documentation strings are now inherited if not overridden.

plus(x) Plus corresponds to the unary prefix plus operator in Python. This operation applies the context precision and rounding, so it is not an identity operation.
