Method # 1: Using List Comprehension + abs()
This task can be accomplished using a list comprehension technique in which we simply iterate over each item and continue to find its absolute value using abs () .
| # Python3 code to demonstrate how it works
# Absolute value of list items
# using abs () + list comprehension
# initialize the list test_list = [ 5 , - 6 , 7 , - 8 , - 10 ]
# print original list print ( "The original list is:" + str (test_list))
# Absolute value of list items
# using abs () + list comprehension res = [ abs (ele) for ele in test_list]
# print result print ( "Absolute value list:" + str (res)) |
Output:
The original list is: [5, -6, 7 , -8, -10] Absolute value list: [5, 6, 7, 8, 10]
Method # 2: Using map () + abs ( )
This task can also be accomplished with map () . As above, the task of map is to perform the task of extending the absolute number logic for each item in the list.
| # Python3 demo code
# Absolute value of list items
# using map () + abs ()
# initialize the list test_list = [ 5 , - 6 , 7 , - 8 , - 10 ]
# print original list print ( " The original list is: " + str (test_list) )
# Absolute value of list items
# using map () + abs () res = list ( map ( abs , test_list))
# print result print ( " Absolute value list: " + str (res)) |
Exit:
The original list is: [5, -6, 7, -8, -10] Absolute value list: [5, 6, 7, 8, 10]
