How Can I Dynamically Import Python Modules by File Path?

Importing Python Modules Dynamically by File Path

Python offers various methods for importing modules based on their full path, enabling access to modules located anywhere within the filesystem with appropriate permissions.

Python 3.5 and Above

import importlib.util
import sys
spec = importlib.util.spec_from_file_location("module.name", "/path/to/file.py")
foo = importlib.util.module_from_spec(spec)
sys.modules["module.name"] = foo
spec.loader.exec_module(foo)
foo.MyClass()

Python 3.3 and 3.4

from importlib.machinery import SourceFileLoader

foo = SourceFileLoader("module.name", "/path/to/file.py").load_module()
foo.MyClass()

Python 2

import imp

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

These methods allow for dynamic module loading based on the specified file path. They are particularly useful when dealing with modules that are not part of the standard Python distribution or are located in custom directories.
