In some cases, it may be simpler to restart the interpreter or modify your program to avoid the need to reload modules. In Python, you can reload a module that has already been imported using the reload() function from the importlib module. In fact, doing import X creates a new symbol ( X) that might be redefined in the code that follows, which is unnecessary (whereas sys is a common. In general, reloading a module can be a useful tool for development and testing, but it should be used with care. A cleaner answer is a mix of Catskul's good answer and Ohad Cohen's use of sys.modules and direct redefinition: import sys Y reload (sys.modules 'X').Y reload () returns the new module. You should be careful when using reload() and test your code thoroughly to ensure that reloading the module does not have unintended side effects. For example, if the module creates threads or modifies global state, reloading the module may not be safe. In some cases, reloading a module can have unexpected consequences or even cause your program to crash.For example, if my_module imports other_module, you may need to reload other_module before reloading my_module. If the module has dependencies on other modules, you may need to reload those modules as well.To work around this, you may need to create a new instance of the class after reloading the module. ![]() Examples of how to reload a python module: Table of contents Reload a module for Python 3.4 or > Reload a module for Python > 3.0 and < 3. For example, if you have created an instance of a class from the module, the instance will still reference the old class definition even after you reload the module. Created Aug Viewed 3966 Comments If you develop your own python module it can be useful to reload it each time you make some change. If you have used functions or classes from the module in your code, reloading the module may not have the desired effect.If the module has not been imported, there is no bytecode to reload. You must first import the module you want to reload.Here are some things to keep in mind when using the reload() function: Once the module is reloaded, any changes you made to it will be reflected in your program. After importing the importlib module, you can use the reload() function to reload the my_module module. In this example, my_module is the module you want to reload. # make some changes to the my_module module Import importlib # import the importlib module Here’s an example of how to reload a module: import my_module # import the module you want to reload The reload() function allows you to reload a previously imported module, which is useful when you have made changes to the module and want to see the changes reflected in your program without restarting the interpreter. In Python, you can reload a module using the reload() function from the importlib module. Fortunately, since I'm testing the code independently, I don't have to do this a ton, but it's still a major hassle.In this article, you will learn how to reload a module in Python. ![]() ![]() It does not refresh the imported modules, so I have to close and re-open ArcMap whenever I change something there. This works out really well but I've run into one frustrating issue during development. Supporting_module.do_something(some_input, some_output) Supporting code is kept in separate unit-testable modules. pyt file itself is simply a wrapper to collect input arguments and define the tools themselves. When using a python toolbox (.pyt) in ArcMap, I'll typically follow a pattern where the.
