如果我正确理解你的问题，在这里你可以试试这个：

players_list=['Cricket','PSL','IPL','t20','shahid afridi','aamer yamin']
cur.execute("SELECT tweet FROM tweets_data")
for row in cur.fetchall():
    if any(True for p in players_list if p.lower() in row.lower()):
        print(row)
    else:
        print ("Else statement")

You seem to have a typo with Circket . Also, there is no need to use indices -- just loop over players_list directly, making sure that both the player and the row have a predictable case. Something like:

players_list=['Cricket','PSL','IPL','t20','shahid afridi','aamer yamin']

cur.execute("SELECT tweet FROM tweets_data")  # Query for getting specific attribute
for row in cur.fetchall():
    for player in players_list: 
        if player.lower() in row.lower():
            print 'list item:', player
            print row
        else:
            print 'Else statement.'
