foo=long_function_name(var_one,var_two,var_three,var_four) 当if语句的条件部分足够长,需要跨多行编写时,值得注意的是,两个字符的关键字(即 if),加上一个空格,再加上一个开括号,会为多行条件的后续行创建一个自然的4个空格缩进。这可能会在if语句内嵌的缩进代码块的可视上产生冲突,后者也会自然地缩进...

So far the scripts we have created have been static in nature. We can allow arguments to be passed on the command line to make scripts that are reusable for different tasks. Two ways to do this are with ARGV and optparse. The ARGV structure is a list containing the name of the program...
