Here is a simple snippet of python code

#!/usr/bin/python
import sys
print sys.argv

Now, if I save this as test.py, make it executable, and run it as

./test.py abc it prints ['./test.py','abc'] which is perfectly sensible.

But if I run it as

./test.py http://www.google.co.in/imgres?hl=en&sa=X&biw=1600&bih=729&tbm=isch&prmd=imvns&tbnid=5FSY1KAB4T48vM:&imgrefurl=http://www.freeganita.com/en/mdlife/4_4.htm&docid=x4Z8mIMpa8FS9M&imgurl=http://www.freeganita.com/en/mdlife/4_4_files/image007.jpg&w=581&h=260&ei=MFaGUMnDHYXSrQfp5YGoDA&zoom=1&iact=hc&vpx=439&vpy=132&dur=1059&hovh=150&hovw=336&tx=71&ty=171&sig=100962344983266552479&page=1&tbnh=123&tbnw=276&start=0&ndsp=28&ved=1t:429,r:2,s:0,i:89

it prints

    you’re not quoting or escaping your url, so you’re getting all kinds of stuff coming from the shell interpretation of your argument. Try

    ./test.py 'http://www.google.co.in/imgres?hl=en&sa=X&biw=1600&bih=729&tbm=isch&prmd=imvns&tbnid=5FSY1KAB4T48vM:&imgrefurl=http://www.freeganita.com/en/mdlife/4_4.htm&docid=x4Z8mIMpa8FS9M&imgurl=http://www.freeganita.com/en/mdlife/4_4_files/image007.jpg&w=581&h=260&ei=MFaGUMnDHYXSrQfp5YGoDA&zoom=1&iact=hc&vpx=439&vpy=132&dur=1059&hovh=150&hovw=336&tx=71&ty=171&sig=100962344983266552479&page=1&tbnh=123&tbnw=276&start=0&ndsp=28&ved=1t:429,r:2,s:0,i:89'
