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

或者

$ python -m cProfile myscript.py

我收到以下错误：

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。我知道它必须是一些非常琐碎的东西，只是无法确定它。

请帮我解决。谢谢

您有一个名为的整数变量id，它掩盖了内置函数id。那是搞砸了cProfile。

重命名您的id变量，cProfile应该可以正常工作。
