how do I do this using python?

Define the get_triples_dict() function which is passed a string of text as a parameter. The function first converts the parameter string to lower case and then retuns a dictionary with keys which are all the unique consecutive three alphabetic characters from the text, and the corresponding values are the number of times the three consecutive alphabetic characters appear in the text. Use the isalpha) method to check if a character is alphabetic or not. The dictionary should only contain entries which occur more than once. After your dictionary has been created and populated, you need to remove any key-value pairs which have a corresponding value of 1. For example, if the text is "Super, duper" the algorithm proceeds as follows Character 's:String is "s", Dictionary is t Character u':String is "su", Dictionary is Character 'p':String is "sup", change string to "up", 'sup": 1) Character'e String is "upe", change string to "pe", Dictionary is f sup 1 upe: 1 CharacterrString is "per", change string to "er", Dictionary is 'sup 1, "upe 1 per'1) Character ',': String is "er", Dictionary is {'sup": 1, upe': 1, 'per': 1} CharacterString is " Dictionary is sup1 upe1, 'per1) Character'd'String is "erd", change string to "rd", Dictionary is 'sup': 1 upe'1 per' 1, erd1) Character'String is "rdu", change string to "du", Dictionary is Character 'p': String is "dup", change string to "up", Dictionary is Character'e String is "upe", change string to "pe", Dictionary is Character'r':String is "per", change string to "er", Dictionary is Remove all entries with a value of 1: upe 2, "per': 2 'sup': 1 upe1 per': 1, erd 1, "rdu': 1 'sup: 1, "upe'1 per' 1, 'erd 1, 'rdu: dup 1) 'sup: 1, "upe'2, 'per' 1, 'erd 1, 'rdu: dup 1) 'sup: 1, "upe'2, 'per' 2, 'erd 1, 'rdu: dup 1) For example, executing the following code
