REG: need of Python Script

I'm new to python. I'm following the book learning python theHard way. In that book I have given a task to perform to search some sample codes of python and practicing it. I searched in Internet but mostly I can find only simple python codes. I need to practice to see how the complex keywords are used in python. Please provide me some links or suggestions to read some complex scripts to practice python, So that it will helpful for me..
