Package

Functions for importing packages or accessing information about packages.

Test

Action Code Details
Check if package or top-level module Name exists 
import importlib.util
importlib.util.find_spec("Name") is not None
Can be used to check for submodules, but this loads the parent import!
Check if package or module Pkg is loaded 
'Pkg' in sys.modules

Extract

Action Code Details
Get file path from package 
from importlib import resources
path = str(resources.files('actionsheets.data').joinpath('python.toml'))
Get file paths from package according to pattern, recursively 
from importlib import resources
from importlib.resources.abc import Traversable

def gather_files(entries: Iterator[Traversable]) -> list[str]:
    files_list = []
    for entry in entries:
        if entry.is_dir():
            files_list += gather_files(entry.iterdir())
        elif entry.name.endswith('.csv'):
            files_list += [entry]
    return files_list

data_root = resources.files('actionsheets.data')
paths = gather_files(data_root.iterdir())
Code could be simplified

Package meta data

Action Code Details
Version of a given package 
from importlib.metadata import version
version('actionsheets')
All package metadata, as dict 
from importlib.metadata import metadata
dict(metadata('actionsheets'))
Conceals duplicate metadata entries

Import

Action Code Details
Import package or top-level module 
import actionsheets
Try import package or top-level module 
try:
    import actionsheetsss
except ImportError as e
    print(e)
Try import package or top-level module, store result in indicator variable 
try:
    import actionsheets
    assert actionsheets
    _no_actionsheets = False
except ImportError:
    _no_actionsheets = True
Try to import submodule, catch error if not found 
try:
    import actionsheets.paper
except ModuleNotFoundError as e:
    print(e)
