Python implements a method of scanning subdirectories and files under a specified directory _python

This article describes using Python to scan files in a specified directory, or a function that matches a specified suffix and prefix. The steps are as follows:

If you want to scan files in a specified directory, including subdirectories, you need to call Scan_files ("/export/home/test/")

If you want to scan a file (such as a jar package) for a specific suffix in a specified directory, including subdirectories, call Scan_files ("/export/home/test/", postfix= ". Jar")

If you want to scan files (such as test_xxx.py) for a specific prefix in a specified directory, including subdirectories, call Scan_files ("/export/home/test/", postfix= "Test_")

The specific implementation code is as follows:

#!/usr/bin/env python
#coding =utf-8
 
import OS
 
def scan_files (directory,prefix=none,postfix=none):
  files_list=[]
   
  for root, sub_dirs, files in Os.walk (directory): For
    special_file in Files:
      if postfix:
        if Special_file.endswith (postfix):
          files_list.append (Os.path.join (root,special_file))
      elif Prefix:
        if Special_file.startswith (prefix):
          files_list.append (Os.path.join (root,special_file))
      else:
        files_list.append (Os.path.join (root,special_file)) return
              
  files_list
