xmlparser.NotationDeclHandler(notationName, base, systemId, publicId) Called for notation declarations. notationName, base, and systemId, and publicId are strings if given. If the public identifier is omitted, publicId will be None.

socket.inet_pton(address_family, ip_string) Convert an IP address from its family-specific string format to a packed, binary format. inet_pton() is useful when a library or network protocol calls for an object of type struct in_addr (similar to inet_aton()) or struct in6_addr. Supported values for address_family are currently AF_INET and AF_INET6. If the IP address string ip_string is invalid, OSError will be raised. Note that exactly what is valid depends on both the value of address_family

class email.charset.Charset(input_charset=DEFAULT_CHARSET) Map character sets to their email properties. This class provides information about the requirements imposed on email for a specific character set. It also provides convenience routines for converting between character sets, given the availability of the applicable codecs. Given a character set, it will do its best to provide information on how to use that character set in an email message in an RFC-compliant way. Certain character s

xmlparser.StartCdataSectionHandler() Called at the start of a CDATA section. This and EndCdataSectionHandler are needed to be able to identify the syntactical start and end for CDATA sections.

curses.ascii.isprint(c) Checks for any ASCII printable character including space.

FTP.sendcmd(cmd) Send a simple command string to the server and return the response string.

class cmd.Cmd(completekey='tab', stdin=None, stdout=None) A Cmd instance or subclass instance is a line-oriented interpreter framework. There is no good reason to instantiate Cmd itself; rather, it’s useful as a superclass of an interpreter class you define yourself in order to inherit Cmd‘s methods and encapsulate action methods. The optional argument completekey is the readline name of a completion key; it defaults to Tab. If completekey is not None and readline is available, command compl

math.log1p(x) Return the natural logarithm of 1+x (base e). The result is calculated in a way which is accurate for x near zero.

netrc.macros Dictionary mapping macro names to string lists.

POP3.dele(which) Flag message number which for deletion. On most servers deletions are not actually performed until QUIT (the major exception is Eudora QPOP, which deliberately violates the RFCs by doing pending deletes on any disconnect).
