此代码是我正在开发的程序的一部分。它使用CSV从文件中读取。这部分代码应该将输入日期与CSV文件中的日期进行比较，并输出任何匹配日期及其携带的信息。这是CSV数据：CSV file 问题是，当我在字段中输入另一个日期时，我希望它删除在代码的for循环中创建的任何标签。 deleteResults函数仅删除最后创建的标签集。有没有办法通过另一个函数删除for循环中创建的所有标签，无论使用for循环创建的标签数量是多少？感谢。

答案 0 :(得分：0)
您会发现该方法与此帖here类似，我给出的示例使用动态生成的小部件。您需要查看.destoy()而不是.configure()
旁注：
我建议使用in来缩短代码，以便缩短代码，因为您正在为不同的实例执行相同的操作。
if accessM.get() in {"1", "01"}:
leMon="January"
另外，正如布莱恩奥克利建议的那样。使用字典。我相信它会是这样的。
date_values = {"01" : ("January", range(1, 31)),
"02" : ("February", range(1, 30)), # Check for leap years
.....}
leMon = date_values[accessM.get()][0]
d = int(accessD.get())
# Checks if day is in month range
leDay = str(d) if d in date_values[accessM.get()][1] else None
