Обновление ярлыка слишком часто

Question

Метка из пакета обновляется каждый раз, когда я ввожу номер. Я знаю, что это намеченный способ работы, но когда я ввожу 9999 при вводе, он обновляется 4 раза, и каждый раз, когда он ищет в словаре 4000-5000 записей, он застревает на 1 секунду. как я могу обновить его только после ввода 4 символов? или обновить, когда я нажму на следующую запись. Я не хочу обновлять его нажатием кнопки. Я заканчиваю с большим количеством ошибок из-за того, что не могу найти ключ

Answer 1

как я могу обновить его только после ввода 4 символов

Просто проверьте, сколько символов было введено, и выполняйте работу только при наличии четырех символов.

def BatchInput(a, b, c): 
    e2 = e2var_get()
    if len(e2) < 4:
        return
    ...
