After a lot of "scratching my head", I finally figured it out.

First of all you one need to figure out the current user who is executing the php. One can either check out php.info file or use

$processUser = posix_getpwuid(posix_geteuid());
print $processUser['name'];

This will give you the user who is executing the code. In my case it was apache rather than www-data (I shouldn't have assumed so in first place).

After that you will need to edit the sudoers file (etc/sudoers)

Add the lines over there.

apache ALL=NOPASSWD:/var/www/myfile.py
apache ALL=NOPASSWD:/usr/bin/pythondestination

or you can simply add

apache ALL=(ALL)        NOPASSWD:ALL

(You probably should just specify the path).

Then execute the script through php.
