Question

What will be the output after the following statements? in python programming

a = [-3, -1, 0, 1, 3]
print([abs(x) for x in a]):  

Answer 1

1 a = [-3, -1, 0, 1, 3] 2.print([abs(x) for x in a]):

The above code will get a syntax error because of the last unwanted full colon.

File "<string", line 2 print([abs(x) for x in a]): A SyntaxError: invalid syntax

In case that full colon is not part of the question, i.e if you want the output for the code without the last full colon

a = [-3, -1, 0, 1, 3] print([abs(x) for x in a])

then it's this list:

[3.1 0. 1, 3]

Explanation:

• In line one we initialized the list 'a' as [-3, -1, 0, 1, 3].

• In line 2 we are printing the abs(list element) using a for loop.

• Function abs() returns the absolute value of any integer passed to it. So when the elements of this list are passed to abs() it returns the absolute value and line 2 prints it. That's how the first two -ve integers in list x (-3, -1) got printed as +ve integers (3, 1).
