i need help fixing this python code

We'll say that a triple in a string is a character that appears three times in a row. Triples may overlap. For example, the string "AAAXBBBBxyz' contains three triples. Write code that counts the number of triples in a string named text and stores the result in a variable named triple_count. Assume that the variable text already has a value. prev char count + 1 if (prev_char_count >= 3): triple_count + 1 else: prev_char count = 1 prevoius_char = text[index] 13 print(triple count) Check My Solution Load My Latest Solution [Reset Test Results: You're using a variable named triple_count. The result is correct for the string 'abcdef". X The result is not correct for the string 'zzz'. The result is not correct for the string 'xxxx'. * The result is not correct for the string 'abcXXXdefYYYghizzzjki'. X The result is not correct for the string 'tttttttttttt
