python - 如何提取 zip 文件夹并查找特定文件名 Python 2

Question

我的代码当前解压缩一个 zip 文件夹并遍历该文件夹中的每个文件。但是，我需要它来读取该 zip 文件夹中名为“file.txt”的特定文件名。我试图只从 zip 文件夹中读取“file.txt”，但它最终会运行该文件夹中的所有文件。有什么建议么？我的代码输出到一个文本文件，我需要它读取的是“file.txt”，但它会读取所有以“.txt”结尾的文件，如实际结果所示

    import re
    import os
    from zipfile import ZipFile
    def pan():
        print("Extract single file from ZIP")
        with ZipFile('input_files.zip', 'r') as zipObj:
            listOfFileNames = zipObj.namelist()
            #zipObj.extractall()
            for fileName in listOfFileNames:
                if fileName.endswith('.txt'):
                    zipObj.read(fileName, 'file.txt') 
    ##def main():
        comma_string = ', '
        outfile = "output2.txt"                 #this will be the filename that the code will write to 
        wp_string = " White Space Detected"          
        tab_string = " tab detected"
        mc_string = " Missing carriage return"
        ne_string = " No Error"                 #If there is no whitespace,tabs, then there is no error
        baconFile = open(outfile,"wt") 
        print('Filename\tLine\tnumber of numbers\tstring separated by a comma\twhite space found\ttab found\tcarriage return found\n')         #This prints the master column in the python shell and this is the way the code should collect the data

            false_string = "False (end of file)"
            carriage_found = false_string 
            sigfigs = ""

            index += 1                            #adds 1 for every line if it finds what the command wants

            sigfigs = (','.join(str(len(g)) for g in re.findall(r'\d+\.?(\d+)?', line )))    #counts the sigsfigs after decimal point 

            print(filename + "\t{0:<4}\t{1:<17}\t{2:<27}\t{3:17}\t{4:9}\t{5:21}"
              .format(index, len(content), sigfigs, str(whitespace_found), str(tab_found), str(carriage_found)))   #whatever is inside the .format() is the way it the data is stored into
            baconFile.write('\n')
            baconFile.write( filename + "\t{0:<4}\t{1:<17}\t{2:<27}\t{3:17}\t{4:9}\t{5:21}"
                        .format(index, len(content), sigfigs, str(whitespace_found), str(tab_found), str(carriage_found)))



    if __name__ == '__main__':

        pan()
