Question
Choose the Correct Answer(s)What will be the output after the following statements?a = [-3, -1, 0, 1, 3] print([abs(x) for x in a])Options[-3, -1, 0, 1, 3][0, 1, 3][3, 1, 0, 1, 3][-1, 0, 1]
Solution 1
The correct answer is [3, 1, 0, 1, 3].
Here's the step by step explanation:
-
The given code is a list comprehension in Python. It's a compact way of creating a new list by performing some operation on each item in an existing list.
-

Solution 2
The correct answer is [3, 1, 0, 1, 3].
Here's the step by step explanation:
-
The given code is a list comprehension in Python. It's a compact way of creating a new list by performing some operation on each item in an existing list.
-
In this case, the operation is
abs(x), which returns the absolute value ofx. The absolute value of a number is its distance from 0 on the number line, regardless of direction. In other words,abs(x)isxifxis positive or zero, and-xifxis negative. -
The existing list is
a = [-3, -1, 0, 1, 3]. So the list comprehension[abs(x) for x in a]creates a new list where each item is the absolute value of the corresponding item ina. -
Therefore, the output of
print([abs(x) for x in a])is[3, 1, 0, 1, 3].
Solution 3
The correct answer is [3, 1, 0, 1, 3]. This is because the abs() function in Python returns the absolute value of the specified number. The absolute value of a number is its distance from 0, regardless of the direction. Therefore, the absolute values of -3, -1, 0, 1, and 3 are 3, 1, 0, 1, and 3 respectively.
