Update the QRcode?

[lewisxy]

This is by far the best QRcode tool in python I can find, except this minor problem...
After I create the object using code = pyqrcode.create("somedata"), I find no way to change the data once the object is created. In other words, there is no function like update(self, data), which allows the data to be updated.

PS. I have tried to change the content through code.content = "something different", but it doesn't change anything. After I read the code I know this is not possible because there is no function in the class QRcode that could update the backend builder class.

I know I can simply create a new object with different content, but isn't it better to reuse the object?

Having an immutable QR Code is a design decision.

An update(self, data) method would require an additional method, like "make(self)" to know when the QR Code should be updated or each invocation of "update(self, data)" would require a new calculation of the internals of QR code (checking the input, calculating the data and error code words, finding a mask, etc.).

Do you think that the object creation is too expensive or why do want an update method?
