A comment starts with a hash character (#
) that is not part of
a string literal, and ends at the end of the physical line. A comment
signifies the end of the logical line unless the implicit line joining
rules are invoked.
Comments are ignored by the syntax; they are not tokens.
一个注释以#
字符(此时, 它不能是串字面值的一部分)开始,结束于该物理行的结尾.如果没有隐式的行连接, 那么注释就意味着该逻辑行的终止.注释为句法分析所忽略, 它们不记作语言符号.
