Side note: You happened to get lucky with P, w, and c, but for the
future, I recommend using forward slashes for your paths:

open("D:/Programming/Python/working_with_files/cities.txt", "r+")

Otherwise, you may run into annoying and hard-to-solve problems. Or
alternatively, you'll upgrade to a newer Python and start getting
warnings, which would at least tell you that there's a problem.
