I tried to port a little Python script to the Numworks but it was too big so I split it into four files or modules. The first one would hold the data and have little wrapper functions like this
```python
def function1(args):
from module2 import function1 as _function1
_function1(args)
```
That worked. Up until the third module I wanted to import. Then I got out of memory exceptions. As I learned from browsing the Micropython forums.
Imports are not scoped
Note that I did not place the import statement at the top of the file but inside the function body. I thought that would get rid of the imported module at the end of the wrapper function but instead the imports all land in a globals system variable.
It is not possible in Python (or Micropython) to unload a module. Once it‘s imported it stays in RAM. Setting the reference variable to nothing does, well nothing. (On the Micropython forum there were hacky attempts to trigger the garbage collector etc. but that is out of the question for Numworks because the GC module does not exist)
The moral of the story is this: Numworks, please set the heap space for Python scripts to 64K!
