When you program with Visual Studio Code (VS Code) and import a module in Python, the code in that module is only executed once, and subsequent imports of the same module will simply use the already imported module without re-executing its code. This means that if you modify a module after it has been imported, the changes will not be applied until you reload the module.
To reload a module in Python, you can use the
importlib module, which provides a function called
reload(). Here’s an example:
import custom_module # ... do some modifications to the custom_module ... import importlib importlib.reload(custom_module)
In this example, we first import the
custom_module module, which contains the code we want to modify. We then make some modifications to the module’s code.
To apply the changes, we use the
importlib module to reload the
custom_module module. We call
importlib.reload(custom_module), which re-executes the code in the
custom_module module, applying any changes we made.
Note that the
reload() function only works with modules that were originally loaded using the
import statement. If the module was loaded using other methods, such as the
__import__() function or the
reload() will not work.
