importlib (Python 2.7 Backport)

Warnings

• breaking This PyPI `importlib` package is a backport specifically for Python versions prior to 2.7 and for Python 3.0. It is completely obsolete and unnecessary for Python 2.7+ and Python 3.1+ where `importlib` is a standard library module. Installing it on modern Python 3 environments provides no benefit and can lead to confusion.
  Fix: For Python 2.7+ and Python 3.1+, `importlib` is a standard library. Do not install this PyPI package. Simply `import importlib` directly.
• deprecated The `importlib` PyPI project has been explicitly archived by its maintainer since November 2017 and is no longer under maintenance. No new releases, bug fixes, or security updates will be provided.
  Fix: Migrate to a supported Python version (Python 3.x) where `importlib` is part of the standard library and actively maintained as part of the CPython project. The functionality provided by this backport (`importlib.import_module()`) is built-in.
• gotcha There is significant confusion between the PyPI `importlib` package (this backport) and the `importlib` module in Python's standard library. The standard library `importlib` is a powerful, actively developed module in all Python 3 versions, offering extensive functionality for programmatic importing, module metadata (`importlib.metadata`), and resource access (`importlib.resources`). This PyPI package only backports a tiny fraction of that functionality.
  Fix: Always confirm whether you need the standard library's `importlib` (which is highly likely for modern Python) or this long-abandoned backport (which is highly unlikely). For Python 3, simply `import importlib`.
• gotcha When performing dynamic imports, be mindful of relative imports. If `importlib.import_module()` is used with a relative name (e.g., `.mymodule`), the `package` argument must be provided as the anchor package name, otherwise an `ImportError` or `ModuleNotFoundError` may occur.
  Fix: When performing relative imports with `importlib.import_module()`, specify the `package` argument, e.g., `importlib.import_module('.relative_module', package='my_package')`.
• deprecated For complex dynamic loading scenarios in Python 3, `importlib.find_loader()` is deprecated since Python 3.4. It should be replaced with `importlib.util.find_spec()`. Similarly, `loader.load_module()` is deprecated since 3.4 and will be removed in 3.15; use `loader.exec_module()` instead.
  Fix: Update code to use `importlib.util.find_spec()` to obtain a `ModuleSpec`, and then `loader.exec_module()` for module execution.

Install

• pip install importlib Install (Python 2.x only)

Imports

• import_module
  wrong:

  from importlib import import_module

  correct:

  import importlib
  module = importlib.import_module('my_module')

  While `from importlib import import_module` is valid for the Python 2.7 standard library and later, the primary use case for this *PyPI backport* was to add `importlib.import_module` where it wasn't natively available, typically accessed as `importlib.import_module()`.

Quickstart

A basic example demonstrating the use of `importlib.import_module()` from this backport. This package is only relevant for very old Python versions. For Python 3, `importlib` is a built-in standard library module.

import importlib

# This PyPI package primarily provides importlib.import_module
# for older Python 2.x environments where it wasn't built-in.
# For Python 3, 'importlib' is a standard library module.

try:
    # Attempt to dynamically import a module
    math_module = importlib.import_module('math')
    print(f"Successfully imported math module. sqrt(16) = {math_module.sqrt(16)}")
except ImportError as e:
    print(f"Could not import module: {e}")
    print("Note: This 'importlib' PyPI package is a Python 2.7 backport and is obsolete for modern Python 3.x.")
