__len__() Return a count of messages in the mailbox.

license credits Objects that when printed, print a message like “Type license() to see the full license text”, and when called, display the corresponding text in a pager-like fashion (one screen at a time).

size Total size of memory blocks in bytes in the new snapshot (int): 0 if the memory blocks have been released in the new snapshot.

AbstractEventLoop.default_exception_handler(context) Default exception handler. This is called when an exception occurs and no exception handler is set, and can be called by a custom exception handler that wants to defer to the default behavior. context parameter has the same meaning as in call_exception_handler().

find_module(fullname) A concrete implementation of Finder.find_module() which is equivalent to self.find_loader(fullname)[0]. Deprecated since version 3.4: Use find_spec() instead.

imap_unordered(func, iterable[, chunksize]) The same as imap() except that the ordering of the results from the returned iterator should be considered arbitrary. (Only when there is only one worker process is the order guaranteed to be “correct”.)

log_error(...) Logs an error when a request cannot be fulfilled. By default, it passes the message to log_message(), so it takes the same arguments (format and additional values).

_get_child_mock(**kw) Create the child mocks for attributes and return value. By default child mocks will be the same type as the parent. Subclasses of Mock may want to override this to customize the way child mocks are made. For non-callable mocks the callable variant will be used (rather than any custom subclass).

string.punctuation String of ASCII characters which are considered punctuation characters in the C locale.

os.path.getsize(path) Return the size, in bytes, of path. Raise OSError if the file does not exist or is inaccessible.
