How do you start a comment in Python code?

• A. Using the double slashes "//"
• B. Using the hash symbol "#"
• C. Using the semicolon ";"
• D. Using the exclamation mark "!"

Answer: (B)

In Python, comments are initiated using the hash symbol "#". When this symbol is placed at the beginning of a line or before the actual code, everything following it on that line is treated as a comment and ignored by the Python interpreter. This is essential for providing explanations or annotations within the code, making it easier for others (or yourself at a later time) to understand the purpose and functionality of various parts of the code. The other options do not function as comment indicators in Python. Double slashes "//" are used for comments in languages like C++ or Java, whereas the semicolon ";" serves as a statement terminator in several languages but is not a comment marker in Python. The exclamation mark "!" does not denote comments in Python either; instead, it's often used in conjunction with other symbols for different purposes in various contexts.
