When I run it, the Ctrl-D doesn't affect the behaviour of Ctrl-C. Can
you confirm that the behaviour is dependent on whether Ctrl-D is used?

Again, if I ‘import readline’ or not, the behaviour is unchanged. Can
you show a specific series of steps that changes the behaviour?

The ‘raw_input’ function uses the ‘readline’ library. That library uses
signal handlers for many of the terminal signals, as documented at
<URL:http://cnswww.cns.cwru.edu/php/chet/readline/readline.html#SEC43>.
