[Tutor] [tutor] Difference between index and find in manipulating strings

[Varsha Purohit]

Hello,
  i have again very basic question in python string management.

I am not able to understand how find and index works and what do they
actually return.

>>> line = "this is varsha"
>>> print line.find("is")
2
>>> print line.rfind("is")
5
>>> print line.rfind("varsha")
8
>>> print line.index("varsha")
8

what does 2 in first line signifies... and why rfind gave 5 as an output...

can anybody pls explain me what exactly is interpreter tryin to return.....
