I am logged in as "myuser" which is also the administrator of the computer.
I have a file on which I have the following rights:
-r--r--r-- 1 myuser staff 167 17 Feb 14:26 my_python.py
However, when I type in python my_python.py on the command line, I still can run the file. Don't I need execute (x) rights in order to do that?!
The only way I cannot run the file is when I change the rights to:
---------- 1 myuser staff 167 17 Feb 14:26 my_python.py
Instead of using Finder aliases, use Terminal to create symbolic links (see man ln for details on usage):
ln -s /path/to/python3.3/binary /usr/local/bin/python
ln -s /path/to/python2.6/binary /usr/local/bin/python2.6
It's usually not a good idea to mess with /usr/bin content (will be wiped out with the next upgrade). Use /usr/local/bin instead and make sure it comes before /usr/bin in $PATH.
Keyboard Maestro can do this using the following macro, which runs chmod +x on each item in the current Finder selection:

Python only requires the file contents to be read.
Recall that Python is an interpreted language and just processes the contents of that file, rather than executing it; python is the executable here! Therefore, calling the interpreter with the file as input/argument does not require other than read permissions (e.g.,
python example.py).
