Using Python (Do not use regular expressions, no tuples, no methods of string, no indexing of strings : str[0] is the first character of string str, str[1] is the second, etc.)

Write a program called CountConsecutiveChars it reads strings from the user until the user presses enter without entering anything. it reports the number of characters that appear consecutively in the string more than once (lets call that a "run") it also prints the length of the largest run. For example if the String is: "aaxbbb", then the sum of all characters that were repeated consecutively is 5 because 'a' repeats 2 times and 'b' repeats 3 times. The largest run was 3 (the b's).

% python3 CountConsecutiveChars.py  enter a string: abc >>>count 0 >>>max 0 enter a string: aabc >>>count 2 >>>max 2 enter a string: aaabc >>>count 3 >>>max 3 enter a string: aaaabcc >>>count 6 >>>max 4 enter a string: aaaaabbc >>>count 7 >>>max 5 enter a string: abcccc >>>count 4 >>>max 4 enter a string:
