python把变量如何写入mysql

GAME_ID = s["resultSets"][0]["rowSet"][i][0]

TEAM_ID = s["resultSets"][0]["rowSet"][i][1]
PLAYER_NAME = s["resultSets"][0]["rowSet"][i][5]

db = MySQLdb.connect("localhost","root","199536abc","test")

cursor = db.cursor()
sql = """INSERT INTO PLAYER(GAME_ID,TEAM_ID,NAME)
VALUES (GAME_ID,TEAM_ID,PLAYER_NAME)"""

try:
# 执行sql语句
cursor.execute(sql)
# 提交到数据库执行
db.commit()
except:
# Rollback in case there is any error
db.rollback()

                现在的问题是sql语句里values后面括号里的三个不是之前定义的GAME_ID,TEAM_ID,PLAYER_NAME,                只能写固定值“21212”，1212，“nick”这样的                求解
