Use python functions in C# by IronPython (error)

Question

I am trying to use my simple python class in C# windows form App by using IronPython. I succeed to use that but after import a random library in python scrip the engine start to gives me an error. So how can I import this library to the C# code ?!

Note my problem start after adding this line to python code ( import random )

My Python code :

    import random 
    
    class Math:
        
        def RandomF(self,a,b):
            return random.randint(a,b)
    
        def Emptyss(self):
            return 3
        
        def sum(self,a,b):
            return a+b
        
        def sub(self,a,b):
            return a-b
        
        def mult(self,a,b):
            return a*b
        
        def devi(self,a,b):
            return a/b
        
        def Max(self,a,b):
            
            if a >b:
                return a
            else:
                return b
            
            def Min(self,a,b):
                if a<b:
                    return a
                else :
                    return b
            

My C# class :
