There is a loop in my python script using nicegui.
the script exec verif_input() without stopping.

You can find my simplified script below :

def mainfct():

    with ui.stepper().props('vertical').classes('w-full') as stepper:

        with ui.step('step 1'):
            with ui.stepper_navigation():
                ui.button('Next', on_click=stepper.next)

        with ui.step('step 2'):
            with ui.stepper_navigation():
                ui.button('Next', on_click=stepper.next)
                ui.button('Back', on_click=stepper.previous).props('flat')

        with ui.step('step 3'):
            with ui.stepper_navigation():
                ui.button('Verif', on_click=lambda: ui.navigate.to('/FTTO_PHASE1_RES_page', new_tab=True)).props('no-caps')
                ui.button('Back', on_click=stepper.previous).props('flat')


    @ui.page('/FTTO_PHASE1_RES_page',title='PHASE1_RES1')
    def PHASE1_RES_page():
        verif_input()


mainfct()

@ui.page('/FTTO_PHASE1_page',title='FTTO_PHASE1')
def PHASE1_page():
    ui.button('GO', on_click=lambda: mainfct()).props('no-caps')

ui.run()

Do you have an idea of the solution ? thank you for your help.
