Regular expressions are for processing strings, not loops. I would loop through the list with a for loop, keeping track of the last value seen and the current count. If the current value is the same as the last, increment the count; if it is different, reset the count. You don't actually have to put the flips into a list, you could count the runs directly as you make the flips.
