如何比较两个csv文件并用python在新文件中写入1或0

Question

我对 python 很陌生，我想问一些问题。 我想比较 2 个 csv 文件。具有逗号分隔形式的所有属性值的源文件。 源csv文件包含这样的

advapi32.dll,comctl32.dll,comdlg32.dll,gdi32.dll,gdiplus.dll,hal.dll,imagehlp.dll,kernel32.dll,mpr.dll,mscoree.dll,msi.dll,msvcrt.dll ,mswsock.dll,ndis.sys,netapi32.dll,ntdll.dll,ntoskrnl.exe,ole32.dll,oleaut32.dll,oledlg.dll,opengl32.dll,psapi.dll,rpcrt4.dll,setupapi.dll,shell32 .dll,shlwapi.dll,tapi32.dll,ucc12.dll,user32,user32.dll,wininet.dll,winmm.dll,winspool.drv,ws2_32.dll

第二个csv文件是

advapi32.dll,gdi32.dll,imagehlp.dll,kernel32.dll,msvcrt.dll,mswsock.dll,ntdll.dll,ole32.dll,oleaut32.dll

如果第二个文件的值包含在源中，我想写 1，否则写 0 到新文件。 输出 csv 文件示例为：

advapi32.dll,comctl32.dll,comdlg32.dll,gdi32.dll,gdiplus.dll,hal.dll,imagehlp.dll,kernel32.dll,mpr.dll,mscoree.dll,msi.dll,msvcrt.dll ,mswsock.dll,ndis.sys,netapi32.dll,ntdll.dll,ntoskrnl.exe,ole32.dll,oleaut32.dll,oledlg.dll,opengl32.dll,psapi.dll,rpcrt4.dll,setupapi.dll,shell32 .dll,shlwapi.dll,tapi32.dll,ucc12.dll,user32,user32.dll,wininet.dll,winmm.dll,winspool.drv,ws2_32.dll

1,0,0,1,0,0,1,1,0,0,0,1,1,0,0,1,0,1,1,0,0,0,0,0 ,1,1,0,0,0,1,1,0,0,1

谁能帮帮我，因为我是 python 编程的新手。

如果我对您的理解正确，那么您较短的 dll 列表是某种“库存”（也称为可能），您想查看较长的列表以查看它是否在较短的列表中。如果这是正确的，那么这样的事情就可以做到（使用 split 和 in 作为 cmets 建议）：

possible = "advapi32.dll,gdi32.dll,imagehlp.dll,kernel32.dll,msvcrt.dll,mswsock.dll,ntdll.dll,ole32.dll,oleaut32.dll"
test = "advapi32.dll,comctl32.dll,comdlg32.dll,gdi32.dll,gdiplus.dll,hal.dll,imagehlp.dll,kernel32.dll,mpr.dll,mscoree.dll,msi.dll,msvcrt.dll,mswsock.dll,ndis.sys,netapi32.dll,ntdll.dll,ntoskrnl.exe,ole32.dll,oleaut32.dll,oledlg.dll,opengl32.dll,psapi.dll,rpcrt4.dll,setupapi.dll,shell32.dll,shlwapi.dll,tapi32.dll,ucc12.dll,user32,user32.dll,wininet.dll,winmm.dll,winspool.drv,ws2_32.dll"

possible_list = possible.split(",")
does_match = []
for t in test.split(","):
    if t in possible_list:
        does_match.append("1")
    else:
        does_match.append("0")
print(",".join(does_match))

这只是你如何处理它的基本想法。我留给您的练习是从文件中读取数据并将其写回，但是为此您可以在 stackoverflow 上找到很多答案。
