Python——找到特定目录下的特定格式文件并修改权限

#Demo: find files ends with '.py' or '.sh' and change its mode executive
import os, stat

file_list = os.listdir('./files') # find all files in dest dir
print(file_list)

dest_files = [x for x in file_list if x.endswith(('.sh', '.py'))]
print(dest_files)  # filter the dest files needded

file_stat = os.stat('./files/mma.py').st_mode
print(file_stat)
os.chmod('./files/mma.py', file_stat | stat.S_IXUSR)  #chmod of specified file
