math.erf(x) Return the error function at x. The erf() function can be used to compute traditional statistical functions such as the cumulative standard normal distribution: def phi(x): 'Cumulative distribution function for the standard normal distribution' return (1.0 + erf(x / sqrt(2.0))) / 2.0 New in version 3.2.

NNTP.quit() Send a QUIT command and close the connection. Once this method has been called, no other methods of the NNTP object should be called.

Cookie.rfc2109 True if this cookie was received as an RFC 2109 cookie (ie. the cookie arrived in a Set-Cookie header, and the value of the Version cookie-attribute in that header was 1). This attribute is provided because http.cookiejar may ‘downgrade’ RFC 2109 cookies to Netscape cookies, in which case version is 0.

class typing.Iterable(Generic[T_co]) A generic version of the collections.abc.Iterable.

object The object the codec was attempting to encode or decode.

empty A special class-level marker to specify absence of a return annotation.

filter(record) Is the specified record to be logged? Returns zero for no, nonzero for yes. If deemed appropriate, the record may be modified in-place by this method.

countTestCases() Return the number of tests represented by this test object, including all individual tests and sub-suites.

class typing.ByteString(Sequence[int]) A generic version of collections.abc.ByteString. This type represents the types bytes, bytearray, and memoryview. As a shorthand for this type, bytes can be used to annotate arguments of any of the types mentioned above.

close() Closes the socket to the remote host.
