sqlite if exist update else insert in python

I am trying to update Count=Count+1 if src_ip already exists, else insert into table.

I was able to do it with UPSERT successfully:

INSERT INTO result('min(_time)', src_ip) VALUES(?,?)ON CONFLICT(src_ip) DO UPDATE SET Count=Count+1;

I am looking for another way to do this without using UPSERT. I tried this :

# Import csv to SQLite    
with open('result5.csv', 'r') as f:
    dr = csv.DictReader(f)
    for i in dr:
        c.execute("UPDATE result SET Count = Count + 1 WHERE src_ip = ?", (i['src_ip'],))
        if c.rowcount == 0:
            c.execute("INSERT INTO result ('min(_time)', src_ip, Count) VALUES (?,?,1)",
                      (i['min(_time)'], i['src_ip']))

The script works with no errors. But I am not getting the result I want either. It does not return anything sadly. I am not sure what I am doing wrong here, why can't I UPDATE or INSERT?

Thank you.
