Python | The absolute value of the list items

| |

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]
