D522 Python for IT Automation - Set 5 - Part 3

Correct Answer: True

The in operator checks membership, and 'a' does appear in 'automation', so it returns True.

Correct Answer: Converts it to the number 3.14

float('3.14') converts the numeric string to the floating-point number 3.14.

Correct Answer: [3, 2, 1]

reversed() returns an iterator in reverse order, and list() collects it as [3, 2, 1].

Correct Answer: 'csv'

Splitting on '.' gives ['data', 'csv'], and index -1 selects the last element, 'csv'.

Correct Answer: True

Python compares numeric values, and 5 equals 5.0, so the result is True.

Correct Answer: The number of times a value appears in the list

list.count(value) returns how many times the given value appears in the list.

Correct Answer: 2

find returns the index of the first occurrence of 'l', which is at position 2.

Correct Answer: 7

Converting a float to int truncates toward zero, so int(7.9) is 7.

Correct Answer: Removes and returns the last item by default

list.pop() removes and returns the last element by default, or the element at a given index if specified.

Correct Answer: Combining input validation, error handling, and logging

Validating inputs, handling errors gracefully, and logging results together make an automation script robust and reliable when run unattended.
