我有一个如下所示的日志文件：

我想写一个python代码，它将读取txt文件并创建一个列表列表，并在每个for循环后打印列表文件。

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

代码的输出是：

但是如果你查看输出，它会在每次在列表中追加一个字符串时打印。我想在每个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

任何人都可以告诉我应该如何实现这一目标？

如果我将print命令放在循环之外，如下所示：

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，在我的代码中应该按以下顺序创建：

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

但是如果你查看我的最后一行日志，你会看到列表序列是：

'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：

我实际上正在浏览应用程序的XML文件，并且我想在每次在XML上找到字符串“list”时创建一个新列表，并且在此之后将立即创建一组我想要的“值”附加在该列表中，然后打印最终列表。然后当它完成时，它将继续查看文件，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。有没有办法实现这个目标？

Answer 1

让我看看我是否正确理解了这一点：你只想在一组“价值观”之后执行一个印刷语句。被解析。这是我的看法：

private func makeLoginRestCall(email:String, password:String){
guard let url = URL(string: "http://-----------/PassengerLogin.php") else {
        return
    }
    var request = URLRequest(url:url)
    request.httpMethod = "POST"
    let emailString : String = "email="
    let parameters = emailString + email+",password=" + password
    request.httpBody = parameters.data(using: .utf8)
    let session = URLSession.shared
    session.dataTask(with:request) {
        (data,response,error) in
        if let response = response {
            print(response)
        }else{
            print("No response")
        }
        if let data = data {
            do{
                let json  = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? NSDictionary
                print(json ?? "No data found")
            }catch{
                print(error)
            }
        }else {
            print("No data found")
        }
    }.resume()}

产生：

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.

我使用OrderedDict，因为您需要保留广告订单。

Answer 2

在每个列表结束后无法打印，因为您的输入未被排序，因此无法知道特定列表是否已结束。

您可以做的就是在整个文件处理完毕后打印列表;为此，请将print语句置于循环之外。

从变量创建List列表并在每个For循环 - Python之后打印最终列表
