Write the code for a mapping that generates a list of the absolute values of the numbers in a list named numbers.

Sagot :

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]
