下面是讲定义一个def函数，isinstance()函数，for in，if else等的运用以及逻辑

复制代码 代码如下:
movies=[\”the holy grail\”,1975,\”terry jone & terry gilliam\”,91,
       [\”graham chapman\”,
       [\”michael palin\”,\”john cleese\”,\”terry gilliam\”,
            \”eric idle\”,\”terry jones\”]]]
def print_lol(the_list):#定义一种函数
        for each_item in the_list:#for in循环迭代处理列表，从列表起始位置到末尾
        if isinstance(each_item,list):#isinstance()检测each_item里每一项
                                              #是不是list类型
            print_lol(each_item)#如果是，调用函数print_lol
        else:print(each_item)#如果不是，输出这一项

print_lol(movies)#在movies列表中调用函数
\”\”\”
之前if else语句不对齐导致报错
