Adapt an iterator to behave like a file-like object in Python

Question

I have a generator producing a list of strings. Is there a utility/adapter in Python that could make it look like a file?

For example,

>>> d         


        

Answer 1

this is exactly what stringIO is for ..

>>> import StringIO
>>> some_var = StringIO.StringIO("Hello World!")
>>> some_var.read(4)
'Hell'
>>> some_var.read(4)
'o Wo'
>>> some_var.read(4)
'rld!'
>>>

Or if you wanna do what it sounds like

Class MyString(StringIO.StringIO):
     def __init__(self,*args):
         StringIO.StringIO.__init__(self,"".join(args))

then you can simply

xx = MyString(*list_of_strings)
