这篇文章主要介绍了Python验证文件是否可读写代码分享，具有一定借鉴价值，需要的朋友可以参考下。

本文分享实例代码主要在实现验证文件是否有读写权限问题，具体如下：

									# Import python libs

									import os

									def is_writeable(path, check_parent=False):

									 '''

									 Check if a given path is writeable by the current user.

									 :param path: The path to check

									 :param check_parent: If the path to check does not exist, check for the

									   ability to write to the parent directory instead

									 :returns: True or False

									 '''

									 if os.access(path, os.F_OK) and os.access(path, os.W_OK):

									  # The path exists and is writeable

									  return True

									 if os.access(path, os.F_OK) and not os.access(path, os.W_OK):

									  # The path exists and is not writeable

									  return False

									 # The path does not exists or is not writeable

									 if check_parent is False:

									  # We're not allowed to check the parent directory of the provided path

									  return False

									 # Lets get the parent directory of the provided path

									 parent_dir = os.path.dirname(path)

									 if not os.access(parent_dir, os.F_OK):

									  # Parent directory does not exit

									  return False

									 # Finally, return if we're allowed to write in the parent directory of the

									 # provided path

									 return os.access(parent_dir, os.W_OK)

									def is_readable(path):

									 '''

									 Check if a given path is readable by the current user.

									 :param path: The path to check

									 :returns: True or False

									 '''

									 if os.access(path, os.F_OK) and os.access(path, os.R_OK):

									  # The path exists and is readable

									  return True

									 # The path does not exist

									 return False
