从变量创建列表列表，并在每个For-Python循环之后打印最终列表

我有一个如下所示的日志文件：

|Label: - Name:locale - Type:
|Label:Main Menu - Name:menu - Type:

|||Label:Load and Save Profiles - Name:menu - Type:

dict = {}

with open("/home/mr/Desktop/git/Squish/parsedXML.txt") as f:

    for line in f:
        if "list" in line:                
            list_title = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title] = []

        if "value" in line:
            list_option = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title].append(list_option)
        test.log(str(dict)) #The print command for the IDE I am using

我想编写一个python代码，读取txt文件，创建列表列表，并在每个for循环之后打印列表文件

这是我写的代码：

dict = {}

with open("/home/mr/Desktop/git/Squish/parsedXML.txt") as f:

    for line in f:
        if "list" in line:                
            list_title = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title] = []

        if "value" in line:
            list_option = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title].append(list_option)
            test.log(str(dict)) #The print command for the IDE I am using

代码的输出为：

但如果您查看输出，它每次在列表中添加字符串时都会打印。我想在每次for循环后打印列表的最终输出。像这样：

Log {'lst_Interface': ['xDSL', 'SFP', 'Ethernet', 'SHDSL']} Aug 28, 2017 11:57:37

谁能告诉我我该如何做到这一点

如果我将print命令放在循环之外，如下所示：

|Label:Main Menu - Name:menu - Type:

|||Label:Load and Save Profiles - Name:menu - Type:

dict = {}

with open("/home/mr/Desktop/git/Squish/parsedXML.txt") as f:

    for line in f:
        if "list" in line:                
            list_title = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title] = []

        if "value" in line:
            list_option = re.search('Label:(.*) - N', line).group(1)
            dict['lst_%s' % list_title].append(list_option)
        test.log(str(dict)) #The print command for the IDE I am using

它打印以下输出：

另一个问题是，当在该列表中创建新列表时，在我的代码中，应按以下顺序创建该列表：

'lst_Interface' > 'lst_xDSL Mode' > 'lst_Vectoring Mode' >  'lst_G.FAST' > 'lst_Auto Re-Sync'

但是，如果您查看日志的最后一行，您将看到列表顺序是：

'lst_Interface' > 'lst_Vectoring Mode' > 'lst_xDSL Mode' > 'lst_Auto Re-Sync' > 'lst_G.FAST' 

如何维护列表的顺序

进一步澄清问题：

---

实际上，我正在浏览一个应用程序的XML文件，每次在XML上找到字符串“list”时，我都要创建一个新的列表，然后立即创建一组“值”，我要将其附加到该列表中，然后打印最终的列表。完成后，它将继续查找文件，当它在XML文件中找到另一个“列表”字符串时，它将创建另一个列表，依此类推。没有办法做到这一点吗？

每个列表结束后都无法打印，因为您的输入没有排序，因此无法知道特定列表是否结束

---

您所能做的就是在处理完整个文件后打印列表；为此，请将您的print语句放在循环之外。

让我看看我是否正确理解了这一点：您希望仅在解析一组“值”后执行print语句。以下是我的看法：

import re
from collections import OrderedDict

history = OrderedDict()

with open("file.txt") as f:
    flag = False
    for line in f:
        if "value" in line:
            list_option = re.search('Label:(.*) - N', line).group(1)
            history['lst_%s' % list_title].append(list_option)
            flag = True
        elif flag:  # executes only if previous line was a 'value' and this one is not.
            print(str(history))  # Replace this print statement with yours.
            flag = False
        if "list" in line:
            list_title = re.search('Label:(.*) - N', line).group(1)
            history.update({'lst_%s' % list_title: []})
    else:
        print(str(history))  # Replace this one as well.

产生：

OrderedDict([('lst_Interface', ['xDSL', 'SFP', 'Ethernet', 'SHDSL'])])
OrderedDict([('lst_Interface', ['xDSL', 'SFP', 'Ethernet', 'SHDSL']), ('lst_xDSL Mode', ['Annex A/M', 'Annex B/J'])])
OrderedDict([('lst_Interface', ['xDSL', 'SFP', 'Ethernet', 'SHDSL']), ('lst_xDSL Mode', ['Annex A/M', 'Annex B/J']), ('lst_Vectoring Mode', ['Disabled', 'Enabled', 'Friendly'])])
OrderedDict([('lst_Interface', ['xDSL', 'SFP', 'Ethernet', 'SHDSL']), ('lst_xDSL Mode', ['Annex A/M', 'Annex B/J']), ('lst_Vectoring Mode', ['Disabled', 'Enabled', 'Friendly']), ('lst_G.FAST', ['Disabled', 'Enabled'])])
OrderedDict([('lst_Interface', ['xDSL', 'SFP', 'Ethernet', 'SHDSL']), ('lst_xDSL Mode', ['Annex A/M', 'Annex B/J']), ('lst_Vectoring Mode', ['Disabled', 'Enabled', 'Friendly']), ('lst_G.FAST', ['Disabled', 'Enabled']), ('lst_Auto Re-Sync', ['On', 'Off'])])

---

我使用了，因为您需要保留插入顺序。

只是一个建议，命名

listoflist

a

dict

会让事情变得有点混乱。谢谢。实际上，一开始我想创建一个列表数组。然后在互联网上搜索如何做到这一点。这就是我想到的。我将在我的最终代码中更改它。请避免编辑您的问题以回答错误的答案，尽量保持问题的简洁明了，否则它会变得更难阅读。这几乎正是我想要的。谢谢。如果您查看结果的第三行和第四行，其中会额外打印一个“[]”。这在前两行中没有出现。我怎样才能避免这些呢？@Russo现在应该被修复了，我刚刚颠倒了两个

if

s.@Russo不用担心，谢谢你将其标记为已接受。顺便说一下，我看到您正在解析一个XML文件，所以我假设您发布的文本文件只是XML文件的表示，管道表示嵌套级别。看起来麻烦太多了如果是这样的话，你应该检查一下，这样你就可以直接解析XML文件了。我也认为我做事情的方式比它应该做的更复杂。一个简短的总结：我已经编写了一个测试脚本，它将遍历应用程序的所有菜单。为此，我已经使用ElementTree生成了文本文件，现在我尝试获取所有分支，因为有不同的方法访问菜单的不同分支，所以我尝试一次对一个分支进行分组。如果我没有具体的问题，我想这不是讨论的好地方。如果我面临更多问题，我将发布一个新问题。再次感谢。
