Creating an array matrix in Python

Question

I'm trying to create a 2-dimensional matrix with an array, but I don't quit understand it yet.

I've tried this:

for i in range(x):
for k in range(y):
array.array('u', [i] : [k])

I'm trying to make an field with x, y as in height and width.

edit:

well, I've changed it now and came to this solution, which fixes my problem

import array
x = int(input('width: '))
y = int(input('height: '))
Matrix = array.array("u", ['.' for i in range(x) for k in range(y)])
Matrix.tounicode
print(Matrix)

With this I'm creating a field as an array, although I have to see how tounicode really works, possible I need a hash-function.

This I believe is your answer. I don't know how to mark as a duplicate.

How to define two-dimensional array in python

• PythonUserNew: But is it an array, or arraylist? Because i want it to have constant runtime. Thats what i dont quit get it yet, it seems i always get arraylist, and not an array.
• Tomaltach: In the case I have linked to it would more resemble a dictionary in the likes of java. But you can look at it as a case of an array inside of an array. e.g. var array = [[0,0], [0,1]]
