Dynamically/Lazily import python module on run-time. Also enables easy to use import path name.

Project description

Lets you dynamically/lazily import python module on run-time, enables easy to use import path name, saves memory. Also makes managing projects easy by not having to worry about nested folder structure producing long import names.

Install

use pip to install:

pip install dynamic-import

Example

./example/sample/__init__.py

from dynamic_import import importer

# Static Importer
from .static import static
# Note
#   This is to demonstrate that you can still import modules directly
#   before "importer()" is called.

# Dynamic Importer
importer(
    __package__,
    {
        '.one': ('a', 'b', 'c'),  # from .one import a, b, c
        '.two': ('x', 'y', 'z'),  # from .two import x, y, z
        '.local': 'internals',    # from .local import internals
        # Note -------^
        #   Here we are using str vs Iterable[str] type since its only
        #   1 value. This will also work.
    }
)

./example/example.py

# Static Import #1
# ----------------
from sample import static
print(static())
print()
# Note
#   Only "sample" & "sample.static" modules are loaded at this point.

# Dynamic Import #1
# -----------------
from sample import a, b, c
print(a())
print(b())
print(c())
print()
# Note
#   Now "sample", "sample.direct" & "sample.one" modules are loaded at this point.

# Dynamic Import #2
# -----------------
from sample import x, y, z
print(x())
print(y())
print(z())
# Note
#   All "sample", "sample.direct", "sample.one" & "sample.two" modules are loaded.

# Dynamic Import #3
# -----------------
from sample import internals
print(internals())
# Note
#   This is to demonstrate you can relatively import one module from another module.
