__eq__(exporter) A memoryview and a PEP 3118 exporter are equal if their shapes are equivalent and if all corresponding values are equal when the operands’ respective format codes are interpreted using struct syntax. For the subset of struct format strings currently supported by tolist(), v and w are equal if v.tolist() == w.tolist(): >>> import array >>> a = array.array('I', [1, 2, 3, 4, 5]) >>> b = array.array('d', [1.0, 2.0, 3.0, 4.0, 5.0]) >>> c = arra

email.utils.formataddr(pair, charset='utf-8') The inverse of parseaddr(), this takes a 2-tuple of the form (realname, email_address) and returns the string value suitable for a To or Cc header. If the first element of pair is false, then the second element is returned unmodified. Optional charset is the character set that will be used in the RFC 2047 encoding of the realname if the realname contains non-ASCII characters. Can be an instance of str or a Charset. Defaults to utf-8. Changed in

sys.set_coroutine_wrapper(wrapper) Allows intercepting creation of coroutine objects (only ones that are created by an async def function; generators decorated with types.coroutine() or asyncio.coroutine() will not be intercepted). The wrapper argument must be either: a callable that accepts one argument (a coroutine object); None, to reset the wrapper. If called twice, the new wrapper replaces the previous one. The function is thread-specific. The wrapper callable cannot define new corou

class asyncio.Event(*, loop=None) An Event implementation, asynchronous equivalent to threading.Event. Class implementing event objects. An event manages a flag that can be set to true with the set() method and reset to false with the clear() method. The wait() method blocks until the flag is true. The flag is initially false. This class is not thread safe. clear() Reset the internal flag to false. Subsequently, coroutines calling wait() will block until set() is called to set the interna

exception ssl.SSLError Raised to signal an error from the underlying SSL implementation (currently provided by the OpenSSL library). This signifies some problem in the higher-level encryption and authentication layer that’s superimposed on the underlying network connection. This error is a subtype of OSError. The error code and message of SSLError instances are provided by the OpenSSL library. Changed in version 3.3: SSLError used to be a subtype of socket.error. library A string mnemon

set_param(param, value, header='Content-Type', requote=True, charset=None, language='', replace=False) Set a parameter in the Content-Type header. If the parameter already exists in the header, its value will be replaced with value. If the Content-Type header as not yet been defined for this message, it will be set to text/plain and the new parameter value will be appended as per RFC 2045. Optional header specifies an alternative header to Content-Type, and all parameters will be quoted as n

_b_base_ Sometimes ctypes data instances do not own the memory block they contain, instead they share part of the memory block of a base object. The _b_base_ read-only member is the root ctypes object that owns the memory block.

@importlib.util.module_for_loader A decorator for importlib.abc.Loader.load_module() to handle selecting the proper module object to load with. The decorated method is expected to have a call signature taking two positional arguments (e.g. load_module(self, module)) for which the second argument will be the module object to be used by the loader. Note that the decorator will not work on static methods because of the assumption of two arguments. The decorated method will take in the name of t

Wave_read.getcompname() Human-readable version of getcomptype(). Usually 'not compressed' parallels 'NONE'.

test.support.run_unittest(*classes) Execute unittest.TestCase subclasses passed to the function. The function scans the classes for methods starting with the prefix test_ and executes the tests individually. It is also legal to pass strings as parameters; these should be keys in sys.modules. Each associated module will be scanned by unittest.TestLoader.loadTestsFromModule(). This is usually seen in the following test_main() function: def test_main(): support.run_unittest(__name__) This
