Python 标签更新过于频繁

每次输入数字时，批次中的标签都会更新。我知道这是预期的工作方式，但当我在条目中输入9999时，它将更新4次，每次它从4000-5000个条目的字典中搜索时，它会被卡住1秒。输入4个字符后，如何使其更新？或在单击下一个条目时更新。我不想一按按钮就更新它。我最后因为找不到钥匙而犯了很多错误

输入4个字符后，如何使其更新

只需检查输入了多少个字符，并且只有在有四个字符时才进行操作

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

def批处理输入（a、b、c）：
e2=e2var_get（）
如果len（e2）<4：
返回
...

减少代码以仅保留重要元素。也许当你减少它时，你就会看到问题出在哪里。顺便说一句：使用

len（text）>=4

检查你是否有4个字符。
