[英]Sort 2D list in Jython/Python
I'm using WLST (python/jython) to get the configuration of some WebLogic resources. 我正在使用WLST(python / jython)来获取一些WebLogic资源的配置。 I loop in the queues of a jms module and for each queue I recover the name and some other parameters. 我循环进入jms模块的队列,并为每个队列恢复名称和其他一些参数。
With this info I build a 2D list that I want to order by queueName. 通过此信息,我建立了要按queueName排序的2D列表。
While I can successfully do it these two ways in the python console: 虽然我可以在python控制台中成功完成以下两种操作:
from operator import itemgetter
L=[["queueName1", 1, 2], ["queueName2", 2, 3], ["queueName3", 4, 1]]
sorted(L, key=itemgetter(0))
or 要么
L=[["queueName1", 1, 2], ["queueName2", 2, 3], ["queueName3", 4, 1]]
sorted(L, key=lambda x: x[0])
The version of python/jython (I don't really know what is used) in my WL server (version 10.3.5) doesn't like this when I use a .py script: 当我使用.py脚本时,WL服务器(版本10.3.5)中的python / jython版本(我真的不知道使用了什么)不喜欢这样:
list2d.sort(key=lambda x: x[0])
I get the error: 我得到错误:
Problem invoking WLST - Traceback (innermost last):
File "/home/user/scripts/pythonscripts/get_jms_config.py", line 98, in ?
File "/home/user/scripts/pythonscripts/get_jms_config.py", line 69, in getInfo
TypeError: sort() takes no keyword arguments
If I try using itemgetter it's no better, as I get the following error: 如果尝试使用itemgetter并没有更好的效果,因为出现以下错误:
Problem invoking WLST - Traceback (innermost last):
File "/home/user/scripts/pythonscripts/get_jms_config.py", line 5, in ?
ImportError: cannot import name itemgetter
Does anybody have any suggestion? 有人有什么建议吗?
Edited: 编辑:
def getQueueInformation():
try:
list2d = []
j = 1
jmsSystemResources = cmo.getJMSSystemResources();
for jmsSystemResource in jmsSystemResources:
queues = jmsSystemResource.getJMSResource().getQueues();
for queue in queues:
# print some information
row = []
row.append(queue.getName())
row.append(str(queue.getDeliveryParamsOverrides().getRedeliveryDelay()))
row.append(str(queue.getDeliveryFailureParams().getRedeliveryLimit()))
list2d.append(row)
j += 1
return list2d
except WLSTException:
print 'an error occurred...',

It sounds like you're running a version of Python before 2.4 which is when .sort(key=...)
was introduced. 听起来好像您正在运行2.4之前的Python版本,当时是引入.sort(key=...)
时候。 You can try using the cmp()
version of .sort()
: 您可以尝试使用.sort()
的cmp()
版本:
list2d.sort(lambda left, right: cmp(left[0], right[0]))
