How to convert string into an object

[Scottyous]

Hi, i wrote a table into a .txt file and when i read the line i want to convert this string into an object.

a table like this one :
[[-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, 0, 1, -1, 0, -1], [-1, -1, -1, 1, 0, -1, -1, -1], [-1, -1, -1, -1, -1, 1, 0, 1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1]]

>>> s = "[[-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, 0, 1, -1, 0, -1], [-1, -1, -1, 1, 0, -1, -1, -1], [-1, -1, -1, -1, -1, 1, 0, 1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1]]"
>>> eval(s)
[[-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, 0, 1, -1, 0, -1], [-1, -1, -1, 1, 0, -1, -1, -1], [-1, -1, -1, -1, -1, 1, 0, 1], [-1, -1, -1, -1, -1, -1, -1, -1], [-1, -1, -1, -1, -1, -1, -1, -1]]

Depending what you're doing, the pickle module could also be worth looking at.
