[Python] Indent and block comments in function

在使用區域註解之後的程式碼會顯示錯誤訊息：

IndentationError: unexpected indent

---

I am using Python 2 /Python 3 and wrote the following:

def arithmetic(A):
     x=1
 """
 Some comments here
 """  
     if x=1:
         x=1
     elif x=2:
         x=2
     return 0

But it has the indentation issue:

if x=1: ^
 IndentationError: unexpected indent

So how to write comments in the function?

---

解法：

def arithmetic(A):
     x=1
     """
     Some comments here
     """  
     if x==1:
         x=1
     elif x==2:
         x=2
     return 0

The """ xxx """ is a docstring. Yes, it can be used as a comment, but it winds up being part of the actual code, so it needs to be indented。

原來註解也要內縮 @_@；
