How To save all the attachments from the mail in the outlook without specifying the attachment name

Question

I am new to python. I am trying to save all the attachment from the email without specifying the attachment name from the outlook.

We need to download the attachment with the subject name.

because attachment can come in any name and also i need to download the attachment only for past 2 days.

Could anyone help me. Below is my code

    from win32com.client import Dispatch
import time
import datetime
import re
outlook = Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder("6")
all_inbox = inbox.Items
val_date = datetime.date.today()
 
sub_today = 'test4'
att_today = '20201018_2.xlsx'    
#att_today = re.match(regex_, )
for msg in all_inbox:
    if msg.Subject.find(sub_today) != -1 and msg.SentOn.date() == val_date:
        break

for att in msg.Attachments:
    if att.FileName == att_today:
        print(att_today)
        break

try:
    print(att.FileName)
    #att.SaveAsFile("C:/Users/Shwettha/Downloads/attachment/"+ att.FileName)
    att.SaveAsFile(os.path.join("D:\Script\Monitoring",att.FileName))
    print("SUCCESSFUL","Attachments Downloaded")
except:
    print("ERROR","Attachment Download Failed")
