循环，验证中的错误[Python]

我正在尝试验证我的python脚本：

def DOBSearch():
loop = True
while loop == True:
    try:
        DOBsrch = int(input("Please enter the birth month in a two digit format e.g. 02: "))
        for row in BkRdr:
            DOB = row[6]
            day,month,year = DOB.split("/")
            if DOBsrch == int(month): 
                print("W")
                surname = row[0]
                firstname = row[1]
                print(firstname, " ",surname)
                addrsBk.close
                loop = False
            else:
                print("1 That was an invalid choice please try again.")
    except:
        print("That was an invalid choice please try again.")

但是，当我尝试测试脚本时，我发现有一个bug/错误，因为我得到了以下输出：

     Please enter the birth month in a two digit format e.g. 02: ergase
That was an invalid choice please try again.
Please enter the birth month in a two digit format e.g. 02: 34
1 That was an invalid choice please try again.
1 That was an invalid choice please try again.
1 That was an invalid choice please try again.
1 That was an invalid choice please try again.
1 That was an invalid choice please try again.
1 That was an invalid choice please try again.
Please enter the birth month in a two digit format e.g. 02: 234567
Please enter the birth month in a two digit format e.g. 02: 02
Please enter the birth month in a two digit format e.g. 02: 02
Please enter the birth month in a two digit format e.g. 02: 02
Please enter the birth month in a two digit format e.g. 02:

如果DOBsrch==int（月）：中的

else

似乎放错了位置。您建议在此处使用try-except检查值的类型，例如int、string等。。。当else确保它是一个有效的月份选择时，请尝试检查引发的异常。通常，您希望避免使用普通的

except

块，而是指定可以从代码中引发的异常类型。如果你捕获了所有内容，你可以隐藏你没有预料到的错误。有人可以发布答案或替代解决方案吗？你知道实际打印的是哪个

print

语句吗？

else

下的那一个，还是

下除

以外的那一个？
