我想连接20个sqlserver,下面是单独连接并运行，怎样一次执行连接20个sql 并在上面执行写好的sql，连接异常时要报错.谢谢
sqlserver='xx.xx.xxx.32'，sqlserver1='xx.xx.xxx.33'，sqlserver2='xx.xx.xxx.34'
try:
conn = pymssql.connect(sqlserver, user, password, database)
sql_path = 'C:\count.sql'
sql = open(sql_path,'r',encoding ="utf-8-sig")
sqltxt = sql.readlines()
sql.close()
sql = "".join(sqltxt)
df = pd.read_sql(sql,conn)
except e
try:
conn1 = pymssql.connect(sqlserver1, user, password, database)
sql_path = 'C:\count.sql'
sql = open(sql_path,'r',encoding ="utf-8-sig")
sqltxt = sql.readlines()
sql.close()
sql = "".join(sqltxt)
df = pd.read_sql(sql,conn1)
except e
