audioop.cross(fragment, width) Return the number of zero crossings in the fragment passed as an argument.

email.header.decode_header(header) Decode a message header value without converting the character set. The header value is in header. This function returns a list of (decoded_string, charset) pairs containing each of the decoded parts of the header. charset is None for non-encoded parts of the header, otherwise a lower case string containing the name of the character set specified in the encoded string. Here’s an example: >>> from email.header import decode_header >>> decod

smtp_state Holds the current state of the channel. This will be either COMMAND initially and then DATA after the client sends a “DATA” line.

write(data) Write some data bytes to the transport. This method does not block; it buffers the data and arranges for it to be sent out asynchronously.

size_diff Difference of total size of memory blocks in bytes between the old and the new snapshots (int): 0 if the memory blocks have been allocated in the new snapshot.

with_netmask A string representation of the network, with the mask in net mask notation.

coroutine read(n=-1) Read up to n bytes. If n is not provided, or set to -1, read until EOF and return all read bytes. If the EOF was received and the internal buffer is empty, return an empty bytes object. This method is a coroutine.

sys.ps1 sys.ps2 Strings specifying the primary and secondary prompt of the interpreter. These are only defined if the interpreter is in interactive mode. Their initial values in this case are '>>> ' and '... '. If a non-string object is assigned to either variable, its str() is re-evaluated each time the interpreter prepares to read a new interactive command; this can be used to implement a dynamic prompt.

inspect.getcomments(object) Return in a single string any lines of comments immediately preceding the object’s source code (for a class, function, or method), or at the top of the Python source file (if the object is a module).

curses.napms(ms) Sleep for ms milliseconds.
