## Sagemath: Is there a way to print out all the elements of a Group or a Ring?

The function print prints its argument and returns None, which is the closest in Python to “not returning anything”. When the return value of a command is None, it does not get displayed. Here however you are building a list of these return values, so you get a list all…

## Substitute variables in an expression in Sagemath

Somewhat similar to this question, I was trying to evaluate a Boolean expression given the right hand side variables in Sage. For simplicity, say, my Boolean expression is, $y=x_0+x_1$. For each of $(x_0,x_1) in {(0,0),(0,1),(1,0),(1,1)}$, I want to evaluate $y$. This is the basic code block to get started. Note…

## How to define a matrix using if and for loops in sagemath?

When constructing a matrix in Sagemath, you can pass in a function that computes its entries, which eliminates the need for explicit (and generally inefficient) loops. This function is defined below as xentries: I used the same conditionals as in your post, but grouped them for readability. def xentries(i, j,…
