An important project maintenance signal to consider for module-hot-reload is that it hasnt seen any new versions released to PyPI in the past 12 months, and. It was originally written for a project in which relatively untrustworthy code might be reloaded during operation. This is a short example of how to (more or less) safely reload a python module. ` statement, those will not automatically update and must be re-imported after reloading the module.Dynamically reload a python module Description: However, if symbols have been imported directly using the `from my_module import. The `importlib.reload()` function can be used to reload a module in Python, and any changes made to the module should be reflected after it is reloaded. ` statement, those will not be automatically updated, and you’ll need to re-import them after reloading the module. ![]() Keep in mind that if you’ve imported any symbols (e.g., functions, classes, or variables) directly using the `from my_module import. ![]() Now, the module `my_module` has been reloaded, and any changes you’ve made to the module should be reflected. Reload the module using `importlib.reload()`: Import the module you want to reload (for this example, I’ll use a hypothetical module called `my_module`):ģ. This example assumes that you have Python version. In Python, you can reload a module using the `importlib.reload()` function, which is available in the `importlib` library. To reload an in-process Python interpreter, see the example Reload Modified User-Defined Python Module. This article will explain how to use it, and what you need to keep in mind when reloading modules. Are you looking for an easy way to update a module in Python? The `importlib.reload()` function can help. ![]()
