3.22.2 Interactive Console Objects
The InteractiveConsole class is a subclass of
InteractiveInterpreter, and so offers all the methods of the
interpreter objects as well as the following additions.
Closely emulate the interactive Python console.
The optional banner argument specify the banner to print before the
first interaction; by default it prints a banner similar to the one
printed by the standard Python interpreter, followed by the class
name of the console object in parentheses (so as not to confuse this
with the real interpreter - since it's so close!).
Push a line of source text to the interpreter.
The line should not have a trailing newline; it may have internal
newlines. The line is appended to a buffer and the interpreter's
runsource() method is called with the concatenated contents
of the buffer as source. If this indicates that the command was
executed or invalid, the buffer is reset; otherwise, the command is
incomplete, and the buffer is left as it was after the line was
appended. The return value is
1 if more input is required,
0 if the line was dealt with in some way (this is the same as
Remove any unhandled source text from the input buffer.

Write a prompt and read a line. The returned line does not include
the trailing newline. When the user enters the EOF key sequence,
EOFError is raised. The base implementation uses the
built-in function raw_input(); a subclass may replace this
with a different implementation.
