What is the correct way to comment a single line in Python?

Question

BlackTom AI · Accepted Answer

The question asks about the proper way to denote a single-line comment in Python. 
Option 1: '// This is a comment' uses two forward slashes, which is the syntax for comments in languages like C++, Java, and JavaScript, not Python. In Python, this would just be treated as a syntax error if used in code without being removed, so this is incorrect for Python.
Option 2: '/* This is a comment */' uses C-style block comments, which Python does not support. Python will interpret the characters as part of the code structure unless they happen to be in a string, so this is not valid Python commenting syntax.
Option 3: '# This is a comment' employs the hash symbol, which is the standard way to start a single-line comment in Python. The interpreter ignores everything on the line following '#', making this the correct convention for single-line comments in Python.
Option 4: '' uses HTML-style comment syntax. Python does not recognize this as a comment indicator; it would be treated as code or produce a syntax error unless inside a string literal. Therefore, this is not a valid Python single-line comment.
In summary, the only option that aligns with Python's commenting conventions is the one that starts with a '#', since Python uses the hash symbol to denote comments and ignore the remainder of the line.
