我正在使用下面的代码并得到如下输出。请提出建议。
def isServerRunning(nodename,servername):
"""Returns a boolean to say if the server is running.
Not 100% accurate but should be close - relies on there only being an mbean for
a server if it's running"""
mbean = AdminControl.queryNames('type=Server,node=%s,name=%s,*' % (nodename,servername))
if mbean:
return True
return False
def chunks(l, n):
return [l[i:i+n] for i in range(0, len(l), n)]
l = ['acsayul33450Node00', 'dmgr', 'acsayul33450Node01', 'gndtaskprd1f1', 'acsayul33450Node01', 'nodeagent', 'acsayul33451Node01', 'gndtaskprd1f2', 'acsayul33451Node01', 'nodeagent']
jvmList1 = chunks(l, 2)
sNameList = []
jvmList2 = []
N = 0
S = 0
for jvms in jvmList1:
N += 1
S = str(N)
jvm = (jvms[1])
node = (jvms[0])
status = "stopped"
jvmList2 = jvm
if isServerRunning(node,jvm):
status = "running"
print("\n")
sNameList.append(" %2s. %s %s %s" % (S, jvm, node, status))
X = 1
while X:
print("\n".join(sNameList))
choice = raw_input("\nEnter your choice [1-%s] : " % (S))
try:
ServerName = jvmList2[choice]
X = 0
except KeyError:
print("\nInvalid entry\n")
print ServerName
输出如下。
wsadmin>execfile('C:\IBM\pyscripts\test\10.py')
1. dmgr acsayul33450Node00 running
2. gndtaskprd1f1 acsayul33450Node01 stopped
3. nodeagent acsayul33450Node01 stopped
4. gndtaskprd1f2 acsayul33451Node01 stopped
5. nodeagent acsayul33451Node01 stopped
Enter your choice [1-5] : 1

最佳答案
ServerName = jvmList2[choice]
您的选择是一个字符串。您应该首先将其转换为 int。
choice = int(raw_input("\nEnter your choice [1-%s] : " % (S)))
