Python Traversal directory tree (files that match output specific suffixes)

The module involved has the OS, fnmatch:1, through the method of the OS module to obtain dir, subdir, files, through the os.path.join can be stitched into the full path;

2, Fnmatch mainly through Fnmatch.fnmatch (name, patterns), in patterns to match the name element, to obtain a specific suffix of the file.

This feature code can be encapsulated for subsequent calls:

　　

1 #!/usr/bin/env python2 ImportOS, Fnmatch3 4 defAll_files (Root, patterns='*', Single_level=false, yield_folders=False):5     #take a pattern out of a string and put it in the list6Patterns = Patterns.split (';')#multiple suffixes can be specified as the type of file to be obtained, through '; ' As separators7      forPath, subdir, filesinchOs.walk (Root):8         ifyield_folders:9 files.extend (subdir)Ten Files.sort () One          forNameinchFiles: A              forPatterninchPatterns: -                 ifFnmatch.fnmatch (name, patterns): -                     yieldos.path.join (path, name) the                      Break -     ifSingle_level: -          Break:

In order to verify the final result, (note that the final result is iterative), I have verified the specific example as follows:

　　

1  for  in All_files ('/usr/local/test', pattern='*.py' ):2     print path
