Actually it's good to see so many replies and different methods and
explanations here.

Also, is there any doc link where I can find all the information about
String object - class and instance methods. Google pointed me to following
two links, but that wasn't helpful for finding instance method for finding
length of a string object (rather than using 'len' function).

- http://docs.python.org/library/string.html
- http://docs.python.org/library/stdtypes.html#string-methods

Finally I figured it out ( __length__() ) thanks to ipython shell env. But
is there any online documentation or interactive reference like ruby-ri?
