This question states a fact about Python syntax and behavior regarding comments.
Since there are no answer options provided to analyze, I will address the given statement directly.
The statement: 'In Python, comments begin with the # symbol and are ignored during execution.'
- The syntax rule in Python is that any text following a # on a line is treated as a comment and is ignored by the interpreter. This means the line is not executed and has no effect on the program’s behavior.
- Examples help illustrate this: a line like '# This is a comment' does nothing at runtime besides being present in the source code for humans; it does not produce outputs or side effects.
- It’s worth noting a couple of edge considerations: the # symbol starts a comment only for the remainder of that line; it does not denote the start of a multi-line comment, since Python does not have a distinct multi-line comment syntax—triple-quoted strings used as docstrings are not comments, though they are ignored if not assigned or used.
- Therefore, the statement is consistent with Python’s behavior and is true as described for single-line comments beginning with # and their being ignored during execution.
- A common misunderstanding would be to treat comments as executable or to confuse them with string literals; however, comments are explicitly excluded from execution and have no effect other than documentation within the source code.
