coroutine acquire() Acquire a lock. This method blocks until the lock is unlocked, then sets it to locked and returns True. This method is a coroutine.

class ctypes.c_wchar Represents the C wchar_t datatype, and interprets the value as a single character unicode string. The constructor accepts an optional string initializer, the length of the string must be exactly one character.

name The name of the module that this loader will handle.

utf8 If False, follow RFC 5322, supporting non-ASCII characters in headers by encoding them as “encoded words”. If True, follow RFC 6532 and use utf-8 encoding for headers. Messages formatted in this way may be passed to SMTP servers that support the SMTPUTF8 extension (RFC 6531).

set() Set the internal flag to true. All coroutines waiting for it to become true are awakened. Coroutine that call wait() once the flag is true will not block at all.

exc_type The class of the original traceback.

UUID.version The UUID version number (1 through 5, meaningful only when the variant is RFC_4122).

is_canonical() Return True if the argument is canonical and False otherwise. Currently, a Decimal instance is always canonical, so this operation always returns True.

types.new_class(name, bases=(), kwds=None, exec_body=None) Creates a class object dynamically using the appropriate metaclass. The first three arguments are the components that make up a class definition header: the class name, the base classes (in order), the keyword arguments (such as metaclass). The exec_body argument is a callback that is used to populate the freshly created class namespace. It should accept the class namespace as its sole argument and update the namespace directly with

identify(x, y) Returns the name of the element at position x y, or the empty string if the point does not lie within any element. x and y are pixel coordinates relative to the widget.
