In python we do like

```julia
from mypython_folder.mypython_script import mypython_function/mypython_class

```

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

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

```

it does not work

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

```

after import the sys

```julia
@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

```julia
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

```julia
@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:

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

```
