I need some help with Python error

[Guylolk]

I'm getting "TypeError: unsupported operand type(s) for *: 'instance' and 'int'"

It looks as if I am not setting a correctly and it would be great if someone could assist me with my problem. Thanks!

The issue here is that you're using the operator * (which is obviously multiplication) to multiply your object GUIFramework with an int.

In the context of what you're trying to do, get the value of the field first. Refer to the TkInter documentation for more info.

[dilettante80]

If you don't want to read docs, you need to only change Display like so:

def Display(self):
        """Called when btnDisplay is clicked, displays the contents of self.enText"""
        a = int( self.enText.get() )
