我们可以通过 next() 函数来访问迭代器: s = [1,2,3] s_2 =iter(s)next(s_2)# 1next(s_2)# 2next(s_2)# 3next(s_2)# raise StopIteration 访问迭代器的时候需要注意下,如果使用 next() 函数访问到对象的末尾还接着访问的话,会引发 StopIteration 的异常。 我们可以通过 try-except 的方式来捕...
During the boot process, the software creates a checksum record of each stage of the boot loader activities. You can retrieve this record and compare it with a Cisco-certified record to verify if your software image is genuine. If the checksum values do not match, you may be ...
