本文实例讲述了Python3实现从指定路径查找文件的方法。分享给大家供大家参考。具体实现方法如下:

这里给定一个搜索路径,根据这个路径请求和请求的文件名,找到第一个符合要求的文件

import os 
def search_file(file_name, search_path, pathsep = os.pathsep): 
  for path in search_path.split(pathsep): 
    candidate = os.path.join(path, file_name) 
    if os.path.isfile(candidate): 
      return os.path.abspath(candidate) 
  return None 
search_path = 'd:\\pm\\pm' 
find_file = search_file('babyos.img', search_path) 
if find_file: 
  print("File 'babyos.img' found at %s" % find_file) 
else: 
  print("File 'babyos.img' not found")

Copy after login

希望本文所述对大家的Python3程序设计有所帮助。
