In this article, I'll show you - through a few practical examples - how to combine a for loop with another for loop and/or with an if statement!
根据Python的缩进规则,如果if语句判断是True,就把缩进的两行print语句执行了,否则,什么也不做。 可以通过下图来简单了解条件语句的执行过程: if 语句 Python中if语句的一般形式如下所示: ifcondition_1:statement_block_1elifcondition_2:statement_block_2else:statement_block_3 ...

因此我们一行只写一个语句,不要试图使用分号将多行语句写在一行。对于if语句、for循环等等,如果其内部的代码只有一行,那么可以写在一行,可以写成if condition: statement或者for i in loop: print(i)这种形式,但是注意如果语句块有多行,再写成这样会给人带来困惑的。
