Names from a module can directly be imported into the importing module's symbol table: It is customary to place all import statements at the beginning of a module or a script. modname.name A module can import other modules. Global variables of a module can be accessed with the same notation as functions, i.e. This is a way to prevent that a global variable of a module accidentally clashes with a user's global variable with the same name. Since version 3.4 you should use the "importlib" module, because imp.reload is marked as deprecated:Ī module has a private symbol table, which is used as the global symbol table by all functions defined in the module. Type "help", "copyright", "credits" or "license" for more information. Alternatively, you can use "imp import reload" and use reload(my_module). You have to execute an "import imp" and use imp.reload(my_module). So it's still possible to reload files as before, but the functionality has to be imported. Since Python 3.0 the reload built-in function has been moved into the imp standard library module. in -> 1 reload (one_time ) NameError: name 'reload' is not defined NameError Traceback (most recent call last) ![]() ![]() The executable application will be created by putting them together. When creating a modular system, several modules are built separately and more or less independently. In other words: Minimization of dependencies is the goal. The focus for this separation should be to have modules with no or just few dependencies upon other modules. Modular programming is a software design technique to split your code into separate parts. There exists a variety of concepts to design software in modular form. Especially if your application has a certain size. If you want to develop programs which are readable, reliable and maintainable without too much effort, you have to use some kind of modular software design. So, what's a must for the hardware is an unavoidable necessity for the software running on the computers. Computers belong to those products which are modularised to the utmost. There is hardly any product nowadays, which doesn't heavily rely on modularisation, like cars and mobile phones. In many cases, they can be even used in other systems as well. ![]() ![]() These components can be independently created and tested. Modular design means that a complex system is broken down into smaller parts or components, i.e. Modular design is an approach which has been proven as indispensable in engineering even long before the first computers. Modular programming is a software design technique, which is based on the general principal of modular design.
