How to use the bpython.repl.Repl.push function in bpython

def push(self, s, insert_into_history=True):
        # curses.raw(True) prevents C-c from causing a SIGINT
        curses.raw(False)
        try:
            return repl.Repl.push(self, s, insert_into_history)
        except SystemExit as e:
            # Avoid a traceback on e.g. quit()
            self.do_exit = True
            self.exit_value = e.args
            return False
        finally:
            curses.raw(True)

def push(self, s, insert_into_history=True):
        # curses.raw(True) prevents C-c from causing a SIGINT
        curses.raw(True)
        try:
            return Repl.push(self, s, insert_into_history)
        finally:
            curses.raw(True)

def push(self, s, insert_into_history=True):
        # Restore the original SIGINT handler. This is needed to be able
        # to break out of infinite loops. If the interpreter itself
        # sees this it prints 'KeyboardInterrupt' and returns (good).
        orig_handler = signal.getsignal(signal.SIGINT)
        signal.signal(signal.SIGINT, signal.default_int_handler)
        # Pretty blindly adapted from bpython.cli
        try:
            return repl.Repl.push(self, s, insert_into_history)
        except SystemExit as e:
            self.exit_value = e.args
            raise urwid.ExitMainLoop()
        except KeyboardInterrupt:
            # KeyboardInterrupt happened between the except block around
            # user code execution and this code. This should be rare,
            # but make sure to not kill bpython here, so leaning on
            # ctrl+c to kill buggy code running inside bpython is safe.
            self.keyboard_interrupt()
        finally:
            signal.signal(signal.SIGINT, orig_handler)
