pylint已经将其检测为问题（从1.7版开始）。
例如，这是我的
tuple.py：
"""Module docstring to satisfy pylint"""def main(): """The main function""" thing = 1, print(type(thing))if __name__ == "__main__": main()$ pylint tuple.pyNo config file found, using default configuration************* Module tupleR: 5, 0: Disallow trailing comma tuple (trailing-comma-tuple)------------------------------------------------------------------Your pre has been rated at 8.00/10 (previous run: 8.00/10, +0.00)$ pylint --help-msg trailing-comma-tupleNo config file found, using default configuration:trailing-comma-tuple (R1707): *Disallow trailing comma tuple* In Python, a tuple is actually created by the comma symbol, not by the parentheses. Unfortunately, one can actually create a tuple by misplacing a trailing comma, which can lead to potential weird bugs in your pre. You should always use parentheses explicitly for creating a tuple. This message belongs to the refactoring checker. It can't be emitted when using Python < 3.0.
