How to include one script into another?

[snippsat]

two.py would have a function receiving a parameter which is a variable set in one.py

Can make a package then can have one import eg import my_pack then can access all from my_pack..
Depends on how your code are,this can tricky and not so easy when new to this.
Example.

myproject/
│
├── my_pack/                 
│   ├── __init__.py 
│   ├── egg.py  
│   ├── spam.py     
│   ├── foo.py

egg.py

# Absolute path when import from a other module inside a package 
from my_pack.spam import spam_var

def egg_func():
    return f'Variable: <{spam_var}> from spam.py'

spam.py

spam_var = 999

foo.py

def foo_func():
    return 'foo'

Here glue it togethere,this make import easy.
__init__.py

from .egg import egg_func
from .foo import foo_func

Usage of this package,see that i can access all from my_pack.

@snippsat ➜ /workspaces/codespaces-blank $ ptpython
>>> import my_pack
>>>
>>> my_pack.foo_func()
'foo'

>>> my_pack.egg_func()
'Variable: <999> from spam.py'

>>> my_pack.spam.spam_var
999
