Python 3 – os.chown() Method
Python is widely used in various fields, including web development, data analysis, artificial intelligence, and many more. Python is an open-source, high-level, and interpreted programming language. It provides various modules to perform various tasks, and one of them is the “os” module. An os module provides a way to interact with the operating system. The os.chown() method is one of the methods of the os module that is used to change the owner of a file or directory.
Syntax
os.chown(path, uid, gid)
Parameters
The os.chown() method takes three parameters:
- path: A path-like object representing the file or directory path whose owner is to be changed.
- uid: An integer representing the user id of the new owner.
- gid: An integer representing the group id of the new owner.
Return Value
The os.chown() method does not return anything. It just changes the owner of the file or directory.
Example
Let’s see an example to understand how the os.chown() method works in Python.
import os
# Get the current owner and group of the file
stat_info = os.stat('test.txt')
print(f"Before changing: Owner: {stat_info.st_uid}, Group: {stat_info.st_gid}")
# Change the owner and group of the file
os.chown('test.txt', 1000, 1000)
# Get the new owner and group of the file
stat_info = os.stat('test.txt')
print(f"After changing: Owner: {stat_info.st_uid}, Group: {stat_info.st_gid}")
Output:
Before changing: Owner: 501, Group: 20
After changing: Owner: 1000, Group: 1000
In the above example, we first get the current owner and group of the file “test.txt”. We then change the owner and group of the file using the os.chown() method. Finally, we get the new owner and group of the file to verify that the os.chown() method has worked correctly.
Exception
If the os.chown() method fails to change the owner or group due to some error, then it raises an OSError with an error message.
Conclusion
In conclusion, we have learned about the os.chown() method of the os module in Python 3. This method is used to change the owner of a file or directory. We have also seen the syntax, parameters, and return value of the os.chown() method. We have also seen an example of how to use this method. We hope this article has helped you to understand the os.chown() method in Python 3.
