在Python中按IP地址对stdout进行排序

我有几种方法是使用多处理模块并行执行的,但是没有按正确的顺序显示输出。例如:

Host:10.76.0.114  Running upon kernel reinstallation for GRUB
Host:10.76.0.114  Running: /sbin/new-kernel-pkg --package kernel --mkinitrd --dracut --depmod --install --multiboot=/boot/xen.gz 3.18.34-20.el6.x86_64

Host:10.76.0.121  Running %pre for the backup-tools
Host:10.76.0.112  Setting up Update Process
Host:10.76.0.121  Running: yum -y -q  update httpd

当我需要类似的东西时:

Host:10.76.0.112  Setting up Update Process
Host:10.76.0.114  Running upon kernel reinstallation for GRUB
Host:10.76.0.114  Running: /sbin/new-kernel-pkg --package kernel --mkinitrd 
Host:10.76.0.121  Running %pre for the backup-tools
Host:10.76.0.121  Running: yum -y -q  update httpd

我试图使用测试脚本创建它,但遇到问题:

import StringIO
import string, sys

stdout = sys.stdout

sys.stdout = file = StringIO.StringIO()

print """
10.76.0.114  Initiate Recovery images download
10.76.0.114  Running: wget -b -N -i /tools/recovery/recovery-templates-url.list -o /tools/recovery/recovery-templates-download.log -P /tools/recovery >/dev/null 2>&1
10.76.0.114  2016-06-30 00:33 Finished Xen Hypervisor '4.2' and StorageAPI '4.2' install
10.76.0.114
10.76.0.113  Preparing...                ########################################### [100%]
10.76.0.113  package 3-2.noarch is already installed


"""

sys.stdout = stdout

l=file.getvalue()
#print l
l=str(l)
l=l.split()
#print l
print sorted(l, key=lambda k:k[0])

我得到下一个输出:

['###########################################', "'4.2'", "'4.2'", '-b', '-N', '-i', '-o', '-P', '/tools/recovery/recovery-templates-url.list', '/tools/recovery/recovery-templates-download.log', '/tools/recovery', '00:33', '10.76.0.114', '10.76.0.114', '10.76.0.114', '10.76.0.114', '10.76.0.113', '10.76.0.113', '10.76.0.113', '2>&1', '2016-06-30', '>/dev/null', 'Finished', 'Hypervisor', 'Initiate', 'Preparing...', 'Recovery', 'Running:', 'Retrieving', 'StorageAPI', 'Xen', '[100%]', 'and', 'already', 'download', 'images', 'install', 'is', 'installed', , 'package', 'wget'

在这种情况下如何按IP地址排序以获得上面提到的正确输出?

请帮忙!

我在这里修改了一些:

import StringIO
import string, sys

stdout = sys.stdout

sys.stdout = file = StringIO.StringIO()

print """
10.76.0.114  Initiate Recovery images download
10.76.0.114  Running: wget -b -N -i /tools/recovery/recovery-templates-url.list -o /tools/recovery/recovery-templates-download.log -P /tools/recovery >/dev/null 2>&1
10.76.0.114  2016-06-30 00:33 Finished Xen Hypervisor '4.2' and StorageAPI '4.2' install
10.76.0.114
10.76.0.113  Preparing...                ########################################### [100%]
10.76.0.113  package 3-2.noarch is already installed


"""

sys.stdout = stdout

text = file.getvalue()
lines = [line for line in text.splitlines() if line]
print sorted(lines, key=lambda line: line.split(' ')[0])  

这是o / p的样子:

>>> for sorted_line in sorted(lines, key=lambda line: line.split(' ')[0]):
...     print sorted_line
10.76.0.113  Preparing...                ########################################### [100%]
