You create a function to calculate the power of a number by using Python. You need to ensure that the function is documented with comments. You create the following code. Line numbers are included…

Question

Options

• AThe string in Line 06 will be interpreted as a comment.
• BThe pound sign (#) is optional for lines 02 and 03.
• CLine 07 contains an inline comment.
• DLines 01 through 04 will be ignored for syntax checking.

• A
  14% (3)
• B
  10% (2)
• C
  76% (16)

Explanation

C is correct because Line 07 (return x ** y # raise x to the y power) places a comment after executable code on the same line - this is the definition of an inline comment in Python. The interpreter executes return x ** y and ignores everything from # onward.

D is correct because Lines 01–04 all begin with #, making them full-line comments. Python's interpreter skips them entirely during parsing and syntax checking - they exist only for human readers.

Why A is wrong: The # on Line 06 is inside double quotes, making it part of a string literal, not a comment. Python only treats # as a comment delimiter when it appears outside of strings, parentheses-enclosed expressions, etc.

Why B is wrong: The # is required for a line to be treated as a comment. Removing it from Lines 02–03 would cause Python to try to parse x is the base as code, resulting in a syntax error.

Memory tip: Think of Python comments as "hash-gated" - the # must be free (outside quotes, not assigned) to open the gate. A # trapped inside a string is just another character, and a # missing from a comment line turns poetry into broken code.
