#Here is the Python program you requested.

@extend
class Frame2D:
    
    COLUMNS_member_end_forces = 'MEMBERID,FXJ,FYJ,MZJ,FXK,FYK,MZK'.split(',')
    
    def list_member_end_forces(self,rs):
        if not hasattr(rs,'member_efs'):
            return []
        mefs = rs.member_efs
        ans = []
        for memb in self.members.values():
            efs = mefs[memb].fefs
            ans.append((memb.id,efs[0,0],efs[1,0],efs[2,0],efs[3,0],efs[4,0],efs[5,0]))
        return ans

##test:
f.list_member_end_forces(rs)

##test:
f.write_table('member_end_forces',ds_name='test-1',prefix=rs.loadcase,record=False,precision=15,args=(rs,))
%cat test-1.d/all/member_end_forces.csv
