Which symbol is used for comments in Python?

Question

BlackTom AI · Accepted Answer

The question asks which symbol is used for comments in Python, and provides four options to evaluate.
Option a: '' This is the syntax used for comments in HTML/XML, not in Python. Using it in Python would be treated as a string or invalid syntax depending on context, so it does not serve as a Python comment marker.
Option b: '#'' This is the standard comment indicator in Python. Any text following this symbol on the same line is ignored by the interpreter, which is the typical behavior for inline comments. This aligns with Python's design for lightweight in-line documentation and notes.
Option c: '/* */' This is the conventional syntax for block comments in languages like C, C++, and JavaScript. Python does not support this style for comments; using it would either cause a syntax error or be interpreted as a division operation and a following token, rather than a comment.
Option d: '//'' This denotes a single-line comment in languages such as C++, Java, and JavaScript. In Python, this sequence by itself does not constitute a comment marker and would typically be treated as a division operator followed by an unexpected token, leading to an error rather than a comment.
In summary, the distinctive Python approach is to use the hash symbol '#', which marks the start of a comment and signals to the interpreter to ignore the rest of the line. The other symbols belong to comment conventions in other languages or to non-comment constructs, and would not correctly serve as Python comments.
