write mariadb table rows query to each file? - shams - Feb-02-2021 I want to query table pop and write each row to a deferent file, this is code, but the code write the last row to all three files: # Create a cursor object cur = conn.cursor() query = f"SELECT user, passwd,server FROM pop" cur.execute(query) for row in cur: list1 = ['1', '2', '3'] for i in range(len(list1)): f = open('mail%s' % i, 'w') print(row[0],row[1],row[2], file=f) RE: write mariadb table rows query to each file? - buran - Feb-02-2021 you write 3 files for every row, overwriting previous files cur = conn.cursor() query = "SELECT user, passwd, server FROM pop" cur.execute(query) for idx, row in enumerate(cur, start=1): with open(f'mail{idx}.txt', 'w') as f: f.write(','.join(row)) I added 'w' mode to open - it was mistake on my part
