Python Comments Review

Which type of comment occupies a single line in Python?

• Multi-line comment

• Inline comment

• Single-line comment

A single-line comment in Python starts with a hash symbol (#) and occupies only one line. This distinguishes it from multi-line comments, which span multiple lines, and other types like inline or block comments.

How are multi line comments enclosed in Python?

• Single quotes

• Double quotes

• Triple quotes

• Parentheses
