包允许我们定义模块的层次结构并使用"."语法,例如from package.module import my_function轻松访问模块。此外,它们还可以轻松地与其他开发人员共享代码。由于每个包都包含一个 pyproject.toml 定义其依赖项的文件,因此其他开发人员不必单独安装所需的包,而只需从其 pyproject.toml 文件中安装该包即可。 工具 许多工具可...

To handle those situations, it’s always a good idea to use the timeout parameter of the run() function. Passing a timeout=1 argument to run() will cause the function to shut down the process and raise a TimeoutExpired error after one second: Python >>> import subprocess >>> ...

import hooks importlib.abc importlib.resources 参考资料 写在篇前 这篇博客的雏形,严格来讲,在我脑海中浮现已有近一年之久,起源于我之前在写一个python模块并用jupyter notebook测试时发现,当在一个session中通过import导入模块,修改模块再次通过import导入该模块时,模块修改并不会生效。至此,通过一番研究发现,python...
