writelines() writes takes an array and writes it to a file, and write() takes a string.

If somone could explain the whole string array idea i would really appreciate it.

Thanks,

um......
considering strings are char array (or array/list of char?) in C/C++

you will get string arrays as array/list of string
or array/list of (array/list of char),
in simpler term = 2 Dimention array of char

string array was how my Software Development lecturer used to describe "array of (array of char)"

by the way, how do I define a multi-dimention array?

in VB
dim my2DAry as Integer(,) = {{1,2},{3,4}}
in C++
int my2DAry[2][2] = {{1,2},{3,4}};
in C#
int[,] myArray = new int[,] {{1,2},{3,4}};

what about Python?

Ah ok, so if i understand you a string array is a list of strings like..

>>> array = ['this', 'is', 'a', 'string', 'array']
>>> array
['this', 'is', 'a', 'string', 'array']
>>>

have I got it?

multi-dimention lists/arrays in Python are really easy..

myarray = [[1, 2, 3, 4, 5, 6, 7, 8, 9], [10, 11, 12, 13, 14, 15, 16, 17, 18, 19]]

and accessing these lists/arrays is even simpler..

myarray[0][0] = 1 and myarray[1][2] = 11

Re: array of array, etc.

Similar to how a numbers are defined: A number is defined to be a plurality of a plurality of a plurality, according to Frege.
