Question

Assume that salary_steps refers to a non-empty list, write a statement that assigns the value 30000 to the first element of this list?

A) Salary_steps[0] = 30000.
B) Salary_steps.insert(0, 30000).
C) Salary_steps.append(30000).
D) Salary_steps[1] = 30000.

Answer 1

The correct answer is option a. To set the first element of the list named 'salary_steps' to 30000, the correct Python statement is 'salary_steps[0] = 30000'. This would directly assign the value to the first element of the list.

Step-by-step explanation:

To assign the value 30000 to the first element of a non-empty list salary_steps, you would use the index of the first element, which is 0. In Python, indexing starts at 0, meaning the first element is accessed using 0 as the index. Therefore, to set the first element of the list salary_steps to 30000, you would write the following statement:

salary_steps[0] = 30000

The correct answer to this question is A) Salary_steps[0] = 30000. The other options provided would either add a new element to the list or modify a different element (not the first one).
