# Input string str = "Computers are useless. They can only give you answers" # Initialize dictionary dic = {} for char in str: dic[char] = 0 # Update char counts in the dictionary for char in str: # char is used as the key # and the value is the count # of that char in the string # Repeated chars hash to the # same position dic[char]+= 1 # Print characters with count > 1 for char, count in dic.items(): if count > 1 and char != ' ': print "%c is repeated %d times" % (char, count) |
