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...
We use theimportcommand to load a specific module to memory in Python. We cannot unimport a module since Python stores it in the cache memory, but we can use a few commands and try to dereference these modules so that we are unable to access it during the program. These methods, howeve...

Python >>> help(sorted) Help on built-in function sorted in module builtins: sorted(iterable, /, *, key=None, reverse=False) Return a new list containing all items from the iterable in ascending order. A custom key function can be supplied to customize the sort order, and the reverse...
Theimportlib.reload()method reloads a previously imported module. The argument to the method must be a module object that has been successfully imported (prior to reloading it). Theimportlib.reload()method is most often used when we have edited the source of the module using an external editor...
