How to F9 Excel book using Python?

Question

I tried to adapt VBA examples from How do you get Excel to refresh data on sheet from within VBA? , they do not work: sheet.Calculate does nothing, other versions of calculate cannot be found...

Answer 1

Adding a CalculateFull macro progrmmatically and calling it solves the problem, but looks convolutive ...

xlmodule = book.VBProject.VBComponents.Add(1) # http://support.microsoft.com/kb/282830 if this line throws an error
xlmodule.CodeModule.AddFromString('Public Sub AnotherCalculateFull() \n\
                                               Application.CalculateFull \n\
                                               End Sub')
