Python 3 - os.chmod() Method
Description
The method chmod() changes the mode of path to the passed numeric mode. The mode may take one of the following values or bitwise ORed combinations of them −
stat.S_ISUID − Set user ID on execution.
stat.S_ISGID − Set group ID on execution.
stat.S_ENFMT − Record locking enforced.
stat.S_ISVTX − Save text image after execution.
stat.S_IREAD − Read by owner.
stat.S_IWRITE − Write by owner.
stat.S_IEXEC − Execute by owner.
stat.S_IRWXU − Read, write, and execute by owner.
stat.S_IRUSR − Read by owner.
stat.S_IWUSR − Write by owner.
stat.S_IXUSR − Execute by owner.
stat.S_IRWXG − Read, write, and execute by group.
stat.S_IRGRP − Read by group.
stat.S_IWGRP − Write by group.
stat.S_IXGRP − Execute by group.
stat.S_IRWXO − Read, write, and execute by others.
stat.S_IROTH − Read by others.
stat.S_IWOTH − Write by others.
stat.S_IXOTH − Execute by others.
Syntax
Following is the syntax for chmod() method −
os.chmod(path, mode)
Parameters
path − This is the path for which mode would be set.
mode − This may take one of the above mentioned values or bitwise ORed combinations of them.
Return Value
This method does not return any value.
Note − Although Windows supports chmod(), you can only set the file’s read-only flag with it (via the stat.S_IWRITE and stat.S_IREAD constants or a corresponding integer value). All other bits are ignored.
Example
The following example shows the usage of chmod() method.
#!/usr/bin/python3
import os, sys, stat
# Assuming /tmp/foo.txt exists, Set a file execute by the group.
os.chmod("/tmp/foo.txt", stat.S_IXGRP)
# Set a file write by others.
os.chmod("/tmp/foo.txt", stat.S_IWOTH)
print ("Changed mode successfully!!")
Result
When we run the above program, it produces the following result −
Changed mode successfully!!
