How use python functions from my python file in Julia?

General Usage
1

In python we do like

from mypython_folder.mypython_script import mypython_function/mypython_class

how do we use PythonCall.jl to do that?
I tried

mypython_function = pyimport("mypython_folder.mypython_script" => "mypython_function")

it does not work

Python: ModuleNotFoundError: No module named 'mypython_folder.mypython_script'

after import the sys

@py import sys
sys.path

Python list: ['~/.julia/packages/PythonCall/XgP8G/python', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python310.zip', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10/lib-dynload', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10/site-packages', 
 '~/百度云同步盘/StudyResearch/AIforLS/Dermatology/code']   # this is the folder/module where all the python files located

In the python interpreter, the current directory . is in the path by default. When calling from Julia you need to add the directory to sys.path explicitly.

and (I think) similarly for PythonCall where you would do

pyimport("sys").path.append(pwd())

(And, of course, you need to do this in python as as well as soon as you want to run code that is not in the current directory or the regular path.)

Thank you for your informative answer,
yeah, I also tried to

@py import sys
sys.path.append(mypythonfolder) 
sys.path
Python list: ['~/.julia/packages/PythonCall/XgP8G/python', 
'~/.julia/environments/v1.8/.CondaPkg/env/lib/python310.zip', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10/lib-dynload', '~/.julia/environments/v1.8/.CondaPkg/env/lib/python3.10/site-packages', 
 '~/百度云同步盘/StudyResearch/AIforLS/Dermatology/code']   <=# this is the folder/module where all the python files located**

but when I tried to access the pythonscript.py in that folder
it will spit:

@py import code
code.anonymize_mrxs
ERROR: Python: AttributeError: module 'code' has no attribute 'anonymize_mrxs'
