You can also do this

>>> import os
>>> st = os.stat("hello.txt")

Current listing of file

$ ls -l hello.txt
-rw-r--r--  1 morrison  staff  17 Jan 13  2014 hello.txt

Now do this.

>>> os.chmod("hello.txt", st.st_mode | 0o111)

and you will see this in the terminal.

ls -l hello.txt    
-rwxr-xr-x  1 morrison  staff  17 Jan 13  2014 hello.txt

You can bitwise or with 0o111 to make all executable, 0o222 to make all writable, and 0o444 to make all readable.
