Write the code for a mapping that generates a list of the absolute values of the numbers in a list named numbers.
Answer (python):
mixednumbers = [49.5, -2, -54.5, -87.6, 17.3, 92, -1.4, 47.7, -27.4, -31.8]
numbers = []
def absolute(num):
num = abs(num)
return num
mappednumbers = map(absolute, mixednumbers)
for i in mappednumbers:
numbers.append(i)
print(numbers)
Explanation (in line numbers):
1 provides the numbers that we will work with in an array called mixednumbers
2 creates an empty array called numbers where we will store the result
4-6 create a function that will take a number, get the absolute value of it, then return it
8 is where we use our function and mixednumbers to create a map named mappednumbers (it contains the numbers in absolute value)
10-11 take each item in the map and append it to our numbers array (printing the map directly will give us a memory address)
12 prints the numbers array, giving us our solution
Output:
[49.5, 2, 54.5, 87.6, 17.3, 92, 1.4, 47.7, 27.4, 31.8]
