Making Choices

number = -2
if number < 0:
    abs_value = -1 * number
elif number > 0:
    abs_value = number
return abs_value


def abs(number):
    if number < 0:
        abs_value = -1 * number
    elif number > 0:
        abs_value = number
    return abs_value

Demonstrate the function.

abs(-5)
abs(10)

And we can then combine this with loops to do the same thing repeatedly.

numbers = [1, 7, -2, -8, 23, 17, -42]

results = []
for item in numbers:
    results.append([abs(item)])

print results
