d Z d d Z d S)r zBase class for InteractiveConsole.
This class deals with parsing and interpreter state (the user's
namespace); it doesn't deal with input buffering or prompting or
input file naming (the filename is always passed in explicitly).

The optional 'locals' argument specifies the dictionary in
which code will be executed; it defaults to a newly created
dictionary with key "__name__" set to "__console__" and key
"__doc__" set to None.

Arguments are as for compile_command().
One several things can happen:
1) The input is incorrect; compile_command() raised an
exception (SyntaxError or OverflowError). A syntax traceback
will be printed by calling the showsyntaxerror() method.
2) The input is incomplete, and more input is required;
compile_command() returned None. Nothing happens.
3) The input is complete; compile_command() returned a code
object. The code is executed by calling self.runcode() (which
also handles run-time exceptions, except for SystemExit).
The return value is True in case 2, False in the other cases (unless
an exception is raised). The return value can be used to
decide whether to use sys.ps1 or sys.ps2 to prompt the next
line.

When an exception occurs, self.showtraceback() is called to
display a traceback. All exceptions are caught except
SystemExit, which is reraised.
A note about KeyboardInterrupt: this exception may occur
elsewhere in this code, and may not always be caught. The
caller should be prepared to deal with it.

This doesn't display a stack trace because there isn't one.
If a filename is given, it is stuffed in the exception instead
of what was there before (because Python's parser always uses
