How to import .py file from another directory? [duplicate]

Question

I have this structure of files (directory and after arrow files):

model -> py_file.py  report -> other_py_file.py 

main __init__.py:

import model import report 

model directory:

import py_file 

report directory:

import other_py_file 

now in other_py_file I want to import py_file, but what ever I try I give error that there is no such module.

I tried this: from model import py_file

Then: import py_file

Looks like these two folders don't see each other. What is the way to import file from other directory? Do I need to specify some additional imports in init.py files?

Answer 1

You can add to the system-path at runtime:

import sys sys.path.insert(0, 'path/to/your/py_file')  import py_file 

This is by far the easiest way to do it.

Answer 2

Python3:

import importlib.machinery  loader = importlib.machinery.SourceFileLoader('report', '/full/path/report/other_py_file.py') handle = loader.load_module('report')  handle.mainFunction(parameter) 

This method can be used to import whichever way you want in a folder structure (backwards, forwards doesn't really matter, i use absolute paths just to be sure).

There's also the more normal way of importing a python module in Python3,

import importlib module = importlib.load_module('folder.filename') module.function() 

Kudos to Sebastian for spplying a similar answer for Python2:

import imp  foo = imp.load_source('module.name', '/path/to/file.py') foo.MyClass()
