使用 python 编辑文本文件中的行

我正在尝试创建一个文件列表，包括其完整地址。它们存储在 CERN 的网格文件访问库中，这意味着我使用 gfal-ls 访问它们，据我所知 gfal-find 不存在。

我当前的 python 2.7 代码是：

lscommand = "gfal-ls root://address/moreaddress/MyFiles | head -20 > MyListName.txt"
os.system(lsCommand)

它创建 MyListName.txt 如下：

file1.root
file2.root
...
file20.root

我现在想要做的是打开此列表并添加 root://address/moreaddress/MyFiles / 在每个文件名之前。

我怎样才能在Python中做到这一点？

I am trying to create a list of files including their full addresses. They're stored on the Grid File Access Library from CERN which means I access them using gfal-ls, and as far as I know gfal-find doesn't exist.

My current python 2.7 code is:

lscommand = "gfal-ls root://address/moreaddress/MyFiles | head -20 > MyListName.txt"
os.system(lsCommand)

which creates MyListName.txt as so:

file1.root
file2.root
...
file20.root

What I now want to be able to do is to open this list and add root://address/moreaddress/MyFiles/ before each filename.

How can I do this in python?

我当前的解决方案如下所示：

lscommand = "gfal-ls root://address/moreaddress/MyFiles | head -20 > MyListName.txt"

FileList = commands.getstatusoutput(lsCommand)[1]
FileList=FileList.split('\n')

with open(ListFileName,"w") as fulllist: 
    for MyFile in FileList:
        fulllist.write("directoryname/"+MyFile+"\n")

My current solution looks like this:

lscommand = "gfal-ls root://address/moreaddress/MyFiles | head -20 > MyListName.txt"

FileList = commands.getstatusoutput(lsCommand)[1]
FileList=FileList.split('\n')

with open(ListFileName,"w") as fulllist: 
    for MyFile in FileList:
        fulllist.write("directoryname/"+MyFile+"\n")
