Also i just alternated the above code to:
# Load'em
for filename in filenames:
try:
# try to insert the file into the database
cur.execute('''INSERT INTO files (url, host, lastvisit) VALUES (%s,
%s, %s)''', (filename, host, lastvisit) )
except pymysql.ProgrammingError as e:
# Insertion failed, file already into database, skip this, go to next
filename
pass
Isn't more compact and straightforward this way?
but i have to set the url's type into unique type for the abpve to work?
