`问题`：

list_links_docs = []
  soup = get_link_decode(URL)
  for link in range(10):
      link = soup.find("a",text="{}".format(link))
      list_links_docs.append(link)
  for link in list_links_docs:
      lis = link.get("href")
      print(lis)

执行这个程序出现错误

Traceback (most recent call last):
  File "D:\APP\PyCharm 2018.1.4\helpers\pydev\pydevd.py", line 1664, in <module>
    main()
  File "D:\APP\PyCharm 2018.1.4\helpers\pydev\pydevd.py", line 1658, in main
    globals = debugger.run(setup['file'], None, None, is_module)
  File "D:\APP\PyCharm 2018.1.4\helpers\pydev\pydevd.py", line 1068, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script
  File "D:\APP\PyCharm 2018.1.4\helpers\pydev\_pydev_imps\_pydev_execfile.py", line 18, in execfile
    exec(compile(contents+"\n", file, 'exec'), glob, loc)
  File "D:/PyDate/Climb_CTOLib.com/Android_Climb2.py", line 72, in <module>
    lis = link.get("href")
AttributeError: 'NoneType' object has no attribute 'get'

`原因`：

下面是list_links_docs获取到的列表数据，第一个数据就出现了None，导致在循环的时候对None处理不了，Get不到内容，导致的Bug


[None, <a href="/android/docs/android-pg-1.html">1</a>, <a href="/android/docs/android-pg-2.html">2</a>, None, None, None, None, None, None, None]

`解决`：

判断是否为None，当出现None时放弃，或者输出什么，就可以解决。

`更改后：`

list_links_docs = []
  soup = get_link_decode(URL)
  for link in range(10):
      link = soup.find("a",text="{}".format(link))
      list_links_docs.append(link)
  for link in list_links_docs:
      lis = link.get("href")
      print(lis)
  for link in list_links_docs:
      if link == None:
          print("逗逼，哈哈哈")
      else:
          lis=link.get("href")
          print(lis)

07022003改

list_links_docs = []
  soup = get_link_decode(URL)
  for link in range(10):
      link = soup.find("a",text="{}".format(link))
      if link == None:
          print("逗逼，哈哈哈")
      else:
          lis=link.get("href")
          list_links_docs.append(lis)
