import ui
from ui import *
def raw(sender):
    bon = sender.superview['view1']
    bon.present('sheet', hide_title_bar=True )
    
def goal(sender):
    bon = sender.superview['view1']
    bon.close()              #error
    
ui.load_view('point').present('sheet', hide_title_bar=True )

PS Sory for my Eanglish

from ui import *
import ui
x = 5
def paper(sender):
    label = sender.superview['textview1']
    label.text = 'ggg',x
ui.load_view('script').present('sheet')

Typeerror: Expected a string
P.S. sory for my English

Thank you
