I am having trouble in importing functions in python module from some other python package-CodePudding

I am using python 3.9 here is the hierachy of my files

- my_arithemtics
     - arthimeticss_my.py
- user_imputs
     - perform_calculations.py

I want import functions in perform_calculations.py from package my_arithmetics and module arthimeticss_my.py

here is the code

arthimeticss_my.py

def my_add(a, b):
    return (a b)

def my_subtract(a, b):
    return (a-b)

perform_calculations.py

from my_arthimetics.arthimeticss_my import *


a = float(input(" Enter the first number: "))
b = float(input( "Enter the 2nd number: "))


calc = input("Enter s for subtract and a for addition: ").lower()
if calc == "s":
    print(my_subtract(a, b))
if calc == "a":
    print(my_add(a, b))

I am getting this error

Traceback (most recent call last):
  File "/home/django_dev/Documents/testing_python/user_inputs/perform_calculations.py", line 1, in <module>
    from my_arthimetics.arthimeticss_my import my_add, my_subtract
ModuleNotFoundError: No module named 'my_arthimetics'

Why am i getting this error there is no need of __init__.py file in newer versions of python

CodePudding user response：

You need to add this package in your python system path run these commands on vs code terminal

PYTHONPATH=$PYTHONPATH:/<path of my_arthimetics>
export PYTHONPATH
echo $PYTHONPATH
