python cProfile 给出“int”；对象不可调用错误

Question

以下脚本运行良好：

$ python myscript.py 

当我尝试使用 cProfile 分析我的代码时，例如：

$ python -m cProfile -s time myscript.py

或

$ python -m cProfile myscript.py

出现以下错误：

Traceback (most recent call last):

TypeError: 'int' object is not callable

我的脚本在这两种情况下都成功运行，只是在后一种情况下它会阻塞 cProfile。我知道这一定是一些非常琐碎的事情，只是无法确定。

请帮我解决。谢谢

您有一个名为 id 的整数变量，它屏蔽了内置函数 id。这搞乱了cProfile。

重命名您的 id 变量和 cProfile 应该可以正常工作。
