请帮我写一个python 给目录写入权限的代码

Sure, here's an example Python code that adds write permission to a directory:

import os

# Path of directory to be given write permission
directory_path = "/path/to/directory"

# Get the current permissions of the directory
permissions = os.stat(directory_path).st_mode

# Add write permission to the directory
os.chmod(directory_path, permissions | stat.S_IWUSR)

print("Write permission has been added to the directory.")

Note that you may need to run this code with root privileges to modify the permissions of certain directories.
