How do you indicate that some text is only a comment in a Python file?

In Python, comments are indicated by using a hash "#" character. When the interpreter encounters this symbol, it disregards everything that follows it on the same line. This allows developers to add explanations, notes, or annotations in their code without affecting execution. It's a fundamental practice in programming to write comments for clarity, making it easier for others (or the original author at a later date) to understand the intent or functionality of the code.

The other suggested methods don't apply to Python; they belong to other programming languages. For instance, some languages use double slashes "//" for single-line comments, while block comments in languages like Java or C use the "/.../" format. The double dash "--" is also a comment syntax specific to SQL and not applicable to Python. Understanding the correct comment syntax is crucial for writing clear and maintainable Python code.
