-- Trailing comma is not always legal in formal parameters list of a Python function.
--  In Python, the argument list is defined partially with leading commas and partially with trailing commas. This conflict causes situations where a comma is trapped in the middle, and no rule accepts it.
--  **Note:** The trailing comma problem is [fixed in Python 3.6](https://bugs.python.org/issue9232). The remarks in [this](https://bugs.python.org/issue9232#msg248399) post discuss in brief different usages of trailing commas in Python.
 
+- 在Python函数的形式参数列表中, 尾随逗号并不一定是合法的.
+- 在Python中, 参数列表部分用前置逗号定义, 部分用尾随逗号定义. 这种冲突导致逗号被夹在中间, 没有规则定义它.(译:这一句看得我也很懵逼,只能强翻了.详细解释看下面的讨论帖会一目了然.)
+- **注意:** 尾随逗号的问题已经在Python 3.6中被[修复](https://bugs.python.org/issue9232)了. 而这篇[帖子](https://bugs.python.org/issue9232#msg248399)中则简要讨论了Python中尾随逗号的不同用法.
