Hello, first off I am using Python 3.2 on Linux Mint 12 64-bit.
I am confused as to why I can not successfully compare a variable that
was created as an octal to a variable that is converted to an octal in a
if statement yet print yields that they are the same octal value. I
think it is because they are transported around within python as a
integer value, is this correct and if so why?
Code example 1: This code works because both are explicitly converted to
Octals.
PATH = '/home/wolfrage/Documents'
DIR_PERMISSIONS = 0o40740
for dirname, dirnames, filenames in os.walk(PATH):
for subdirname in dirnames:
#list each subdirectory in this directory.
full_path = os.path.join(dirname, subdirname)
print(full_path)
stat_info = os.stat(full_path)
uid = stat_info.st_uid
gid = stat_info.st_gid
#TODO: Group and User ID Check
#TODO: Directories need the right Masks, and then read, write, and
# execute permissions for User(Owner), Group and Others
#TODO: UMask is seperate from permissions, so handle it seperately.
if oct(stat_info.st_mode) != oct(DIR_PERMISSIONS):
#TODO: Fix User Read Permissions
print(str(oct(stat_info.st_mode)) + ' Vs ' +
str(oct(DIR_PERMISSIONS)))
os.chmod(full_path, DIR_PERMISSIONS)
print(subdirname + ' has bad user permissions.')
Code Example 2: This code does not work because we do not use an
explicit conversion.
PATH = '/home/wolfrage/Documents'
DIR_PERMISSIONS = 0o40740
for dirname, dirnames, filenames in os.walk(PATH):
for subdirname in dirnames:
#list each subdirectory in this directory.
full_path = os.path.join(dirname, subdirname)
print(full_path)
stat_info = os.stat(full_path)
uid = stat_info.st_uid
gid = stat_info.st_gid
#TODO: Group and User ID Check
#TODO: Directories need the right Masks, and then read, write, and
# execute permissions for User(Owner), Group and Others
#TODO: UMask is seperate from permissions, so handle it seperately.
if oct(stat_info.st_mode) != DIR_PERMISSIONS:
#TODO: Fix User Read Permissions
print(str(oct(stat_info.st_mode)) + ' Vs ' + str(DIR_PERMISSIONS))
# The Above print statement shows that DIR_PERMISSIONS is
printed as an
# Integer. But Why does Python convert a explicitly created
Octal to an
# Integer?
os.chmod(full_path, DIR_PERMISSIONS)
print(subdirname + ' has bad user permissions.')
