Count elements in a list only if they are following each other and are similar

[law]

Thanks, let me try this

can you give me an example want do you want as result ??

I want python to count only if the fruits are similar and consecutive.
in this case the count should be 3 (it should only count the 'apple','apple','apple' in the code since they are similar and consecutive. It should ignore the other apple since there is no similar consecutive element
