Problem:
 Score : 100 points    Problem Statement CODE FESTIVAL 2016 is going to be held. For the occasion, Mr. Takahashi decided to make a signboard.  He intended to write CODEFESTIVAL2016 on it, but he mistakenly wrote a different string S . Fortunately, the string he wrote was the correct length.  So Mr. Takahashi decided to perform an operation that replaces a certain character with another in the minimum number of iterations, changing the string to CODEFESTIVAL2016 .  Find the minimum number of iterations for the rewrite operation.      Constraints  S is 16 characters long.  S consists of uppercase and lowercase alphabet letters and numerals.         Input Inputs are provided from Standard Input in the following form.  S       Output Output an integer representing the minimum number of iterations needed for the rewrite operation.        Sample Input 1 C0DEFESTIVAL2O16      Sample Output 1 2  The second character 0 must be changed to O and the 14 th character O changed to 0 .       Sample Input 2 FESTIVAL2016CODE      Sample Output 2 16

Solution (Python):
s = list("CODEFESTIVAL2016")

num = 0
for i, c in enumerate(s):
    if c != t[i]:
        num = num + 1
        
print num
