继续检查所有实例的版本，哪怕有一个实例在python中引发错误

Question

我有一个函数，我试图在其中获取数据库的版本。我有多个实例，并且我能够连接所有实例。如果任何数据库没有连接，或者由于某种原因命令失败，无法继续到下一个数据库，我将面临的问题。我只想让它一直持续到最后一次

def dbversion(user_suffix=None):
try:
db_name_list = abc.getdbstring(env_name=None)
for dbname in db_name_list:
connection = Connection(dbname)
cursor = connection.cursor()
version = connection.version
print(" " + version + " ")
except:
print("Fail")

Answer 1

您可以将try块放入循环中：

def dbversion(user_suffix=None):
db_name_list = abc.getdbstring(env_name=None)
for dbname in db_name_list:
try:
connection = Connection(dbname)
cursor = connection.cursor()
version = connection.version
print(" " + version + " ")
except:
print("Fail")
