Matching two files based on a spited elements

[tester_V]

Greetings!
I'm trying to find lines from one file in another file.
I have to do that by matching timestamp.
Lines look like this:
File 1

\\D1376\d$\logs\BBLog.100.xml,05/13/2021 00:01:23
\\D1376\d$\logs\BBLog.11.xml,05/27/2021 15:11:03
\\D1376\d$\logs\BBLog.1.xml,05/28/2021 17:02:03
\\D1376\d$\logs\BBLog.10.xml,05/27/2021 15:22:15

File 2

\\D1376\d$\logs\BBLog.100.xml,05/13/2021 00:01:23
\\D1376\d$\logs\BBLog.11.xml,05/27/2021 15:11:03
\\D1376\d$\logs\BBLog.1.xml,05/29/2021 18:04:02
\\D1376\d$\logs\BBLog.10.xml,05/29/2021 17:02:11

I have to split lines in File-1 and use split elements to match lines in File-2.
for some reason, I cannot print lines that are not in both files.

Here is a code I got:

tod1376 = 'C:\\01\\fileD1376.txt'  
yrd1376 = open ('C:\\02\\fileY1376.txt','r') 
yrd = yrd1376.readlines()

with open (tod1376,'r') as tod :
    for lntod in tod :
        lntod=lntod.strip()
        *whocares,sp_lntod = lntod.split(",")
        sp_EL1 = sp_lntod
        sp_EL1=str(sp_EL1).strip()

        for lnyrd in yrd :          
            lnyrd=lnyrd.strip()
            found = re.search(sp_EL1,lnyrd)  
            print(f" Fund matched- -{lntod}")
            if not found :
               print(f" Not Matched ++ {lntod}")

Thank you!
