Python import module from path | Example code

How to import a Python module given the full path?

The python module is a kind of code file containing a set of functions, classes, and variables definitions. With the module, you can make code reusable and easy to understand. To use module code you have to import it.

Here are some methods to import the module by using its full path:

  • sys.path.append() Function
  • importlib Package
  • SourceFileLoader Class

Example import module from a path in Python

Simple examples code: consider this is project file and modules structure:-

Python import module from path code for all example

var = "Hello main file"
num = 9876543210

def greeting(name):
    print("Hello, " + name)

Using sys.path.append() Function

The path variable contains the directories the Python interpreter looks in for finding imported modules in the source files.

import sys

# appending a path

from modules import main


Output: 9876543210

Using importlib Package

The importlib.util is one of the modules included in this package that can be used to import the module from the given path.

import importlib.util

spec = importlib.util.spec_from_file_location("main", "modules/")

foo = importlib.util.module_from_spec(spec)



Output: Hello main file

Using SourceFileLoader Class

SourceFileLoader class is an abstract base class used to implement source file loading with the help of load_module() function which imports the module.

from importlib.machinery import SourceFileLoader

# imports the module from the given path
foo = SourceFileLoader("main", "modules/").load_module()


Output: Hello, Kevin
