Example 1

The abs() function in Python takes the absolute value of a number

>>> abs(3)
3
>>> x = -3
>>> abs(x)
3

We want to translate the abs() function to assembler language. First think how we would do it in Python if we didn’t have the built in function:

if x < 0:
    x = -1 * x

Now how would we write this in assembler language?

Example 2

How would we write the following Python code in assembler?

n = 3
sum = 0
while n >= 0:
    sum = sum + n
    n = n - 1

Example 3

How would we write the following Python code in assembler?

if x == 0:
    y = 3
else:
    y = 5
z = z + y

We will intialize x, y, and z by hand in the simulator to test our code.
