I'm using Python in VS code. I am experiencing the error "no module named 'ch6'" when trying to import the functions from one file to another, where the files are located in two different folders.

I have two folders:

1. "ch6" – which contain the file "RandomCharacter.py". This file has the functions I want to import.
2. "ch7" – which contain the file "CountLettersInList.py" trying to import the functions from "RandomCharacter.py".

If I try to import the functions with the code:

import ch6.RandomCharacter

I get the error: "No module named 'ch6'"

If I use the code:

import RandomCharacter

I get the error: "No module named 'RandomCharacter'"

However, if I copy CountLettersInList.py from folder ch7 to folder ch6, the import works just fine with the code:

import RandomCharacter

So why can't it import the functions successfully when the files are in two different folders?

CodePudding user response：

The python import system can be annoying. Correct me if I'm wrong in any assumption I make! So what I understand is you're trying to import a RandomCharacter.py into a file located ch7/CountLettersInList.py?

The reason you can't import RandomCharacter.py into CountLettersInList.py is because what CountLettersInList.py can see is only in ch7. It can't even see the folder ch6.

Solution: You have to go up one directory to see ch6. In order to do that tack these lines of code into CountLettersInList.py:

import sys

sys.path.append("..")

This goes up one directory to search for modules!

CodePudding user response：

Add the following code in CountLettersInList.py, then you can import successfully.

import sys
sys.path.append("./")
