Because the constructor method is automatically initialized, we do not need to explicitly call it, only pass the arguments in the parentheses following the class name when we create a new instance of the class. If we wanted to add another parameter, such asage, we could do so by also ...
This method returns a new DataFile instance with the same file path, effectively opening a new file handle. When you call copy.copy() on instances of your updated class, Python will invoke this special method instead of relying on the generic implementation from the copy module: Python >>>...
An Explanation of the Python Class Example The "Self" Parameter Firstly, note that there is a difference between the method signature declared in the class and the method signature that is used by the programmer to call the function. For instance, theget_colourmethod as defined in the class ...
