   class Results:
        Product: [str]
        Total_Value: [int]
        Quantity: [int]
        ProductID: [str]
    
        def __init__ (self, Product: str, Total_Value: int, Quantity: int, ProductID: str):
                self.Product=Product
                self.Total_Value=Total_Value
                self.Quantity=Quantity
                self.ProductID=ProductID
    
     
    
    
    r=Results("hello",1.88,3.888,888)
    print(r.ProductID)
    print(type(r.ProductID))  # why is thie not a string? ? This prints 'int' but ProductID should be string
    print(type(r.Total_Value))  # why is this not an int? This should be 'int' but Total_Value is 'float'


 
    

In c#, the output is correct and I was expecting something similar in Python

void Main()
{
    var b =new Bunny();
    b.Name="Tom";
    b.number=3;
    b.number2=3;
    
    Console.WriteLine(b.number.GetType()); //this prints Int64 as it should
    Console.WriteLine(b.number2.GetType()); //this prints Double as it should
    
    
}

public class Bunny
{
    public string Name;
    public System.Int64 number;
    public double number2;
 
}
