So, in the Python program filemy_rand_int.pywe would import therandommodule to generate random numbers in this manner: my_rand_int.py importrandom Copy When we import a module, we are making it available to us in our current program as a separate namespace. This means that we will hav...
Python's syntax allows for code to be significantly shortened by using something calledmodules.Similar to header files in C++, modules are a storage place for the definitions of functions. They are separated into common uses, such as the time module, which provides functions for time related use...
Python offers three different modules in the standard library that allow you to serialize and deserialize objects: The marshal module The json module The pickle module In addition, Python supports XML, which you can also use to serialize objects. The marshal module is the oldest of the three li...
How to call a function In the previous sections, you have seen a lot of examples already of how you can call a function. Calling a function means that you execute the function that you have defined - either directly from the Python prompt or through another function (as you will see in...

Python >>>importimportlib>>>importlib.import_module("hello")Hello, World!<module 'hello' from '/home/username/hello.py'> Theimport_module()function imports a module, bringing its name to your currentnamespace. It also runs any executable code that the target module contains. That’s why yo...
Just keep in mind that a {% load %} statement will load tags/filters for the given Python module name, not the name of the app. To be a valid tag library, the module must contain a module-level variable named register that is a template.Library instance, in which all the tags and ...
