这是我的项目请理解我是一个初学者。
问题：每次user_input为Y，break为N时，我必须从这行for k, v in d.items() :重复。我不知道我是否可以从行号或从for或从上一行的while重复。
也许我可以在for之前输入def，或者有任何方法可以从任何地方重复。
谢谢你的阅读。

elif action.lower() == 'add':
        table = input ('Select desired table number: \n - ...')
        fulltab = 'T' + table
        with open(fulltab + '.txt', 'w+') as f :
            for k, v in d.items() :
                print(k, v)
            #print('Select codes: \n -...')
            addprod = input('Insert order. \n - ...')
            for k, v in d.items() :
