streamlit multipage: How to import module from different directory

I am trying to build a multipage dashboard where each page uses functions written in a separate .py files. Title_page.py can read function (called 'add_two()') from func_1.py without any problem. However, Page2.py can't seem to read function (called 'multiply_two()') from func_2.py under p2_functions folder, which is placed inside the pages folder. It throws an error saying:

ModuleNotFoundError: No module named 'p2_functions'

I think it's because streamlit ignore anything other than .py files inside the pages folder, but I don't know how then I could call modules and read functions from other .py files or from other folders.

Here's what I have in the Page2.py:

import streamlit as st
from p2_functions.func_2 import multiply_two

st.markdown("# Page 2 ")
st.write(multiply_two(10 * 20))

Here's the tree of the structure:

├── Title_page.py
├── func_1.py
└── pages
    ├── Page2.py
    └── p2_functions
        └── func_2.py

You need to insert the p2_functions folder path into Page2.py if they are from different folders. E,g

import sys
# Insert functions path into working dir if they are not in the same working dir
sys.path.insert(1, "C:/<p2_functions folder path>/") # Edit <p2_functions folder path> and put path

from func_2 import multiply_two

That is the way streamlit can recognise other files from other paths

from pages.p2_functions.func_2 import multiply_two

Imports in Streamlit always work relative to the directory where you run streamlit run ..., so in your case the root of your directory.
