![]() ![]() full stop, comma, or question mark)ĭef decode (self,morse_code_sequence): character = list(self.the_dict.keys()) code = list(self.the_dict.values()) reverse_dict = dict(zip(code,character)) # Error check 1, checking for invalid characters (i.e. Morse Code sequences must end with a punctuation mark (i.e.User can only enter Morse Code Representation that has been pre-defined (e.g.We will also include the error checks we have implemented previously in our Simple Morse Code Decoder mainly: the Morse Code sequence) which works similarly to calling a function and passing a value through it. This means that to call this method, we will have to pass a variable through this method (i.e. Note that in this method, other than defining self, we added another morse_code_sequence. The last method we will define in this class is the decoding of the Morse Code itself called decode (self, morse_code_sequence). Image by author - Python output of Decoder class Notice that my_dict now is an object of class Decoder. Once we have defined the above two methods, we can try displaying the dictionary structure we have defined earlier by assigning a variable name to the class and printing the result. def _str_ (self): dict_str = "" for key,value in self.the_ems(): dict_str += "Character: " + str(key) + " ->" + " Code: " + str(value) + "\n" return dict_str We will add a _str_ (self) method which works the same way as print(variable), but allows us to customize the way the results will be displayed. With just the _init_ (self) method, we cannot display any results if we assign a variable to this class. The next essential method in a class creation is returning/printing the output. As we are adding sentences analysis checks too, we have also added three punctuation marks “. Remember that we chose to use a dictionary structure to store our Morse Code representation in Python, where each alphabet or number is represented by a series of ‘0’s and ‘1’s. This is the essential method for object creation and it usually initialize the values of the instance variables of each object. ![]() We will build a class called Decoder and it will contain several methods, with the first being _init_(self). A simple explanation about Python class is that it defines a set of instance variables (data values to be represented for each object) and a set of methods (operations) that can be applied to the objects. One major difference between this decoder and the previous one is that we will be using Python class to build our decoder and the respective analysis checks. Furthermore, we can implement checks in the decoder to inform us of the frequencies in which each alphabet/number, word, or sentence type have been decoded. In this post, we will improve our simple Morse Code Decoder to be able to decipher sentences as well. Image by author - Python output of Simple Morse Code Decoder
