Installation and use of Python modules

We know that the use of functions not only reduces the workload, but also makes the code more concise and easier to maintain. But if in anotherA file, we want to use a function defined in the previous file, what should we do? We need to weighDo you want to implement the previous function again? And when we're implementing a very complex feature, even if this featureBroken down into smaller functions, the required code is still large, causing the entire file to be difficult to maintain. So is the
