2.1.7 空行 Blank lines

A logical line that contains only spaces, tabs, formfeeds and possibly a comment, is ignored (i.e., no NEWLINE token is generated). During interactive input of statements, handling of a blank line may differ depending on the implementation of the read-eval-print loop. In the standard implementation, an entirely blank logical line (i.e. one containing not even whitespace or a comment) terminates a multi-line statement.

一个仅包括空白, 制表符, 换页符和可能的注释的逻辑行, 是被忽略的(就是说没有NEWLINE语言符号产生). 在交互式输入语句时, 空行的处理可能不同, 依赖于输入-计算-输出(read-eval-print)循环的实现方式. 在标准实现中, 一个纯粹的空行(即不包括任何东西,甚至注释和空白)才结束多行语句.
