os.chown(path, uid, gid);
### Parameters

* **uid** -- User ID to own the file
* **gid** -- Group ID to own the file
### Return Value
This method has no return value.
### Example

## Example
#!/usr/bin/python
# -*- coding: UTF-8 -*-
import os,sys
# Assume /tmp/foo.txt file exists.
# Set owner ID to 100
os.chown("/tmp/foo.txt",100, -1)
print"Permission modified successfully!!"
The output of the above program is:
