Python Learning

[KeNtUrKeY]

Hi everybody,
Im pretty new (or u can say that completely new) to python and i try to learn from the very basic. I try to create grid data structure from array. Here i have some code, would you mind to look at it and give me an instruction:



import math

class Grid(object):
def __init__(self, width = 10, height = 10):
self.width = width
self.height = height
self.size = size
self.grid = []
cell_value = 0

.....

then i got stucked, i would like to print out this array and then save it into text file! i look some place and it gave me this



import numpy as np
x = np.arange(20).reshape((4,5))
np.savetxt('test.txt', x)

but i dont know how to print it then save it into text file
if i have value with coordinate (x,y) later, can i change it in text file? and how?

thank you very much, it will be helpful

By grid data structure I suppose you mean a 2 dimensional array.
So self.grid should be:


self.grid = [[]]

So to print it out you should do something like this:



for i in self.grid:
for k in i:
print k



Writing it to a file should be easy, the harder part will be to read it back.
