The module that we want to reload should have already been imported previously in the program.It is advised to import the module at the top of the program.The Python reload module is used to reload any module in the Python program.It is not supported for Python 2.x versions. Q: Which Is the Minimum Version of Python Required to Use the Python Reload Module?Ī: The Python reload module feature has been added in Python 3.3, thus we need Python 3.3 or above installed in our system to use the Python reload the module. In Python, modules are objects (values) and are handled like other objects. The Python code for a module named aname normally resides in a file named aname.py, as covered in Module Loading. Rather than running a Python file, in Python REPL one may just input commands to see the results getting displayed immediately.Ī: The Python module refers to an arbitrary object with named attributes that can be used for binding and references. The Python REPL is used by developers all over the world for communicating with the Python Interpreter. This also provides an implementation that is easier to comprehend than one implemented in a programming language other than Python.Ī: The Python REPL stands for Read, Evaluate, Print, and Loop. FAQsĪ: The importlib package is used to provide the import statement's implementation in our Python program, making it portable for other Python interpreters. Now the im.reload(exampleModule) will reload the exampleModule thus when exampleModule.show() is called it will display "Hello world!". In the above code, we have imported the reload module in our program using importlib. Note: It is advised to import the module at the top of the program. In order to load a module in Python, we need to use the import keyword followed by the module name. In this section, we will learn how to load a module in Python. Other references of the old objects (like names external to the module) are not necessarily referred to the new objects and must be updated in each namespace where they occur if that is required.The names in the module namespace is changed to new object if any.The old objects are only reclaimed after their reference counts reach zero.However, the init function of the modules is not loaded again. The python module’s code is recompiled and the module-level code is re-executed, defining a new set of objects which are bound to names in the module’s dictionary by reusing the loader which originally loaded the module.The Python reload module returns a module object. The Python reload module helps us achieve this without making us leave the Python interpreter. The Python reload module helps in cases where we are trying to use a newer version of any module and the existing version of that module had already been edited using any external editor. Python Reload ModuleĪs discussed earlier, the Python reload module is used to reload a module that has previously been imported into the Program. Thus we use the Python reload modules to make sure that the modules are being reloaded. The Python reload module is useful in situations like an interactive session where we are frequently running any test script because in such cases we always use the module's first version even if any changes have been made in the code. The Python reload module is used in reloading any module that has previously been imported into the program.
