Solved: python class with optional arguments

The main problem with classes with optional arguments is that it can be difficult to determine at compile time whether a particular argument is required or not. This can lead to errors when the class is used, for example if an argument is missing.

class MyClass:
    def __init__(self, arg1, arg2=None):
        self.arg1 = arg1
        self.arg2 = arg2

This code creates a class called MyClass. The __init__ method takes two arguments, arg1 and arg2. If no value is specified for arg2, it defaults to None. The __init__ method sets the value of self.arg1 to arg1 and self.arg2 to arg2.


In Python, classes are a way to group related variables and functions together. A class can be thought of as a template for creating objects. Classes can be defined in a number of ways, but the most common way is to use the keyword class followed by a list of variable and function definitions.

When a class is created, it is automatically given a name (in this example, we’ll call our class “Person”). The name of the class is also used as the name of the object that is created when the class is instantiated. To create an object using our Person class, we would use the following code:

>>> import person >>> ‘John’


Arguments in Python are handled by the function call. The first argument is the function name, followed by the arguments.
