String methods

Here are some possible manipulations using string methods:

>>> a = 'java python c++ fortran'
>>> a.isalpha()
False

a.isalpha() is False because of the spaces and '++'.

>>> b = a.title()
>>> b
'Java Python C++ Fortran'
>>> c = b.replace(' ', '!\n')
>>> c
'Java!\nPython!\nC++!\nFortran'
>>> print(c)
Java!
Python!
C++!
Fortran!
>>> c.index('Python')
6
>>> c[6:].startswith('Py')
True
>>> c[6:12].isalpha()
True

(Note that \n is a single character.)
