# some examples of string methods:

>>> S = 'hello World!'
>>> S = S.capitalize()
>>> S
'Hello World!'


>>>S.endswith('World!')
True


>>> list = dircache.listdir('Pictures')
>>> pictures = {}
>>> i = 0
>>> for x in list:
...     if x.endswith('.jpg'):
...             pictures[i]=x
...             i += 1


>>> S = 'test'
>>> D = '$'
>>> D.join(S)
't$e$s$t'


>>> S = S.replace('Hello','Goodbye')
>>> S
'Goodbye World'
>>> S.split()
['Goodbye', 'World']
>>> S.split('o')
['G', '', 'dbye W', 'rld']
>>> S.replace('o','x',2)
'Gxxdbye World'

# there is also a string module with a string replace 
import string
>>> import string
>>> S = 'somestring'
>>> string.replace(S,'s','x')
'xomextring'



>>> S = 'Goodbye World'
>>> where = S.find('od')
>>> where
2

>>> S[2]
'o'

>>> S[2:]
'odbye World'

>>> S[:2]
'Go'

>>> list(S)
['G', 'o', 'o', 'd', 'b', 'y', 'e', ' ', 'W', 'o', 'r', 'l', 'd']
