Hello everyone.

Chancing to (r\\, '') or (\\\\, '') did not help.

I know that there were more outcome. I would only let see that on the python prompt the \ is deleted and if I use Eclipse the / stays when I use the text from alice in wonderland.

And im still wondering why this happens.
Maybe put the text from alice into the python prompt and look what happens.
