Can you provide a the Python program you requested given the following:
I am working on the file "Devel/V05/Frame2D_Output.ipynb".
The first task is:
$P-\Delta$ Forces
See module ..._Display
All Results
Can you write Python program for it?

#Here is the Python program you requested.

class Frame2D:
    
    def write_results(self,ds_name,rs):
        self.write_table('node_displacements',ds_name=ds_name,prefix=rs.loadcase,record=False,
                         precision=15,args=(rs,),makedir=True)
        self.write_table('reaction_forces',ds_name=ds_name,prefix=rs.loadcase,record=False,

                             precision=15,args=(rs,))

##test:
f.reset()
f.input_all()
rs = f.solve('One')
f.write_results('test-1',rs)
