控制权转移到下一个条件评估器:elif income < 30000。这个评估为True,因此块#2被执行,因此,Python 在整个if/elif/elif/else子句之后恢复执行(我们现在可以称之为if子句)。if子句之后只有一条指令,即print调用,它告诉我们我今年将支付3000.0的税款(15,000 * 20%)。请注意,顺序是强制性的:if首先出现,然后(可选...

This argument works the same as the equivalent pwd argument in .read(). You can also use .open() with the "w" mode. This mode allows you to create a new member file, write content to it, and finally append the file to the underlying archive, which you should open in append mode:...
