这是我当前的代码。我想检查两个值（行）以检查文件中的匹配项。

def checkOS():
    fid1 = open("C:/Python/NSRLOS.txt", 'r')
    fid2 = open("C:/Python/sha_sub_hashes.out", 'r')
    outdata = open("osMatches.txt", 'w')
    line1 = fid1.readline()
    line2 = fid2.readline()
    while(line1 and line2):
        xline= line1.split(',')[1]
        yline = line2.split("|")[3]
        zline = xline.replace('"','')
        if (yline == zline):
            outdata.append([yline , zline])
            print xline, zline

if __name__=="__main__":
    checkOS()

唯一的问题是我不确定我写的是什么，if 语句之前的所有代码都只是重新格式化以便能够从行的索引中提取。我想知道的是我使用的语句是否在这种意义上有效并且有效？然后我想输出相等的值。以下是文件中的一些行：

现在您可能不会在这几行中找到任何直接匹配项，但我知道在该行的某个地方至少会有一个匹配项，因为我在浏览文件时看到了这一点。

你可能正在寻找这样的东西：

使用with()它会自动为您关闭文件。

def checkOS():
    with open("C:/Python/NSRLOS.txt") as fid1,open("C:/Python/sha_sub_hashes.out") as fid2,open("osMatches.txt", 'w') as outdata:
        for xline,yline in zip(fid1,fid2):  #zip fetches lines from both files one by one                                           
            xline= xline.split(',')[1]      #use itertools.izip instead of zip if you're on python 2.x
            yline = yline.split("|")[3]
            zline = xline.replace('"','')
            if yline == zline:                
                outdata.write("{0}{1}\n".format(yline , zline)) #use write to write the data back

if __name__=="__main__":
checkOS()
