How to create a variable on sage?

Question

Create a variable called “weights”. This variable will be a list of lists. The “zeroth” list will be a list of all the weights from node zero to all the other nodes. The “first” list will be a list of all the weights from node one to all the other nodes.

Using weights from my list:

[0,1] = 24

[0,2] = 16

[0,3] = 4

[0,4] = 1

[1,0] = 24

[1,2] = 5

[1,3] = 1

[1,4] = 6

[2,0] = 16

[2,1] = 5

[2,3] = 15

[2,4] = 7

[3,0] = 4

[3,1] = 1

[3,2] = 15

[3,4] = 2

[4,0] = 1

[4,1] = 6

[4,2] = 7

[4,3] = 2

Answer 1

Looks like a Javascript object. Give it a name, like weights.

weights { [0,0], [0,1],,,,,,} it is a list of 2 dimensional arrays or tuples. I don't know about 'sage' but objects typically are lists or dictionaries or arrays in various forms. You just have to look at the syntax. And to be compatible with other languages, the format will look similar. Open a JSON file and look at it.
