Create a class Geld where objects correspond to amounts in Euros, e.g., € 10.67 and € 456.89

Instance Variables

There are two instance variables:

• an int centen (cents)
• an int euros

Methods

• The class contains an extensive constructor with the only argument being amount. The constructor initializes the instance variables based on the object type.
  • If amount is an int, it’s used to initialize the euros instance variable. The centen instance variable is set to 0. If the parameter is less than 0, the following text will be displayed in the console:

    Negative amounts are not allowed

  • If amount is a float, the part before the decimal point is used to instantiate the euros instance variable, and the part after the decimal point is used for the centen instance variable. If the parameter is less than 0, the following text will be displayed in the console:

    Negative amounts are not allowed

  • If amount is a Geld object, the euros and cents of the Geld object are used to initialize the euros and cents.

  • If amount is a str, the given string represents the amount in the format € XX..X,YY (comma always present). From this string, values are extracted for the instance variables. If the parameter contains an invalid string, the following text will be displayed in the console:

    Incorrect Geld string format

• Getters for the two instance variables
• A method __str__ that returns the amount as a string in the format € [euros].[cents]. Note: Make sure to test your method to work even for Geld objects where cents < 10.
• A method multiply with an argument of type int n. The method multiplies the object calling the method by n and returns the result as an object.
• A method add with an argument of another Geld object. The method adds the specified object to the calling object and returns the result.
