基于Python的文件搜索器，用于Windows，用于ArcMap目录中的损坏数据源

Question

我的目标是拥有一个可以在ArcMap中运行的程序，生成缺少数据源名称的.txt文件，然后再次提取（只有数据源名称）用于目录搜索，我已经研究过了os.walk，但我非常困惑。到目前为止，我所完成的是一个可以在ArcMap中运行的程序，用于生成缺少数据源名称和原始路径的.txt文件。我缺少的是能够仅提取数据源名称，并在整个目录中搜索其当前位置，该位置将被写入另一个文本文件。有谁知道这是否可能？到目前为止，我的代码如下：

    def execute(self, parameters, messages):
#   Identifies broken file names in Table of Contents (TOC)
    mxd = arcpy.mapping.MapDocument("current")
    brokenlist = arcpy.mapping.ListBrokenDataSources(mxd)
    for brokenItem in brokenlist:
        arcpy.AddMessage(brokenItem.dataSource)

#   Path for writing .csv files and searching
    path = r"C:\ENGR597\Project"

#   Opens file to write
    f = open(path + '/Project_Test.txt', 'w')

#   Writes file for arcpy.AddMessage(brokenItem.name)
    for brokenItem in brokenlist:
        f.write(brokenItem.dataSource)

#   Opens text file to be read
    f= open('C:\ENGR597\Project\Project_Test.txt', 'r')

#   Extracts data source file name out to be used in a search (what I am missing)


#   Walks through directory to find file (preliminary code, that I was testing and didn't get far with)
    path = r"C:\ENGR597\Project"
    def walk_through_files(path, file_name='.pyt'):
        for (dirpath, dirnames, filenames) in os.walk(path):
            for filename in filenames:
                if filename.endswith(file_extension):
                    yield os.path.join(dirpath, filename)
                    f = open(path + '/Project_Test2.txt', 'w')
                    f.write(dirpath, filename)
    return

最后，这是使用代码时生成的当前文本文件（只需要为搜索提取的源文件名）的示例：

C:\ENGR597\Project\GIS\Shapefiles\City and Town Points\City and Town 
Points.shpC

提前谢谢大家。我从不觉得python会让人头疼。
