printNow(header())

The program is starting now, prepare to be slain
Starting Health is: 99
Monster attacks for: 38
Remaining Health is: 61
>>>
Next Attack Incoming!
>>>
Current Health is: 61
Monster attacks again for: 23
After that we are left with 38 HP

*None*

为什么我没有这个，我认为它与我的printNow命令有关，但我不确定我做错了导致实际的无值..：/

我试图正常运行它，但我一直得到None值，因为我在列表中注释掉了我的行

当你这样做时：

printNow(header())

header()的结果会传递给printNow，因为header()会返回None，显然会打印return None，因为最后隐含header每个功能。

只需拨打header()：

即可将其替换

{{1}}

为什么我得到的值为None？
