PKG Extraction. PEP 420 -- Implicit Namespace Packages | Python.org Python module pkgutil get_loader() 177: 0: Python program to check leap year. Intended use is to place the following code in a package's __init__.py: If dirname is a string, a PEP 302 importer is created that searches that directory. This is a wrapper for the loader get_data API. PEP 420 was accepted as part of Python 3.3. For example, pkgutil supports *.pkg files; setuptools doesn't. Likewise, setuptools supports inspecting zip files, and supports adding portions to its _namespace_packages variable, whereas pkgutil doesn't. the -m option. The table shows that pkgutil interacts favorably with PEP 420 in python 3. The parent directory name .. is not allowed, and nor is a rooted name (starting with a /). The parent directory name .. is not allowed, and nor is a rooted name (starting with a /). Because Python is a "batteries included" language, the tools you need to use ASTs are built into the standard library. The new code above loops through all packages with the walk_package function in the pkgutil standard library module and tries to import it using the import_module on the package name plus package as a string. FYI, I created issue 15299 and issue 15297 which also relate to pkgutil.walk_packages() not working correctly in Python 3.3 -- even with the caveat added by Brett. It both excludes modules it should include, and includes modules it should exclude. The package argument should be the name of a package, in standard module format (foo.bar).The resource argument should be in the form of a relative filename, using / as the path separator. class pkgutil. It allows to keep __init__.py modules. The primary tool to work with ASTs is the ast module. assertEqual ( res1, RESOURCE_DATA) res2 = pkgutil. For example, pkgutil supports *.pkg files; setuptools doesn't. Likewise, setuptools supports inspecting zip files, and supports adding portions to its _namespace_packages variable, whereas pkgutil doesn't. 225: 0: Python program to check largest number of three numbers: 169: 0: Python Program to get prime numbers between intervals: 185: 0: Lambda Function with examples: 182: 0: Python .

Here are the examples of the python api pkgutil.walk_packages taken from open source projects. . import pkgutil res = pkgutil.get_data ('sound.effects', 'cool_effects/collection_effects.csv') And standard module format means what you use with import, so it requires __init__.py file. I need to import a list of modules in a local package and return their items with pkgutil. The name argument specifies what module to import in absolute or relative terms (e.g. While it is rather trivial to implement the proposed functionality - all that's required here is to eliminate the check for __init__.py from pkgutil._iter_file_finder_modules - this would have undesired impacts on, e.g., pydoc.apropos: This function would then recursively report *any* directory/subdirectory on sys.path . . The importlib module includes functions that implement Python's import mechanism for loading code in packages and modules. This repository generates a pip-installable package, published on PyPI as tzdata. class pkgutil. Author: Chris Jerdonek (chris.jerdonek) *. The package argument should be the name of a package, in standard module format (foo.bar).The resource argument should be in the form of a relative filename, using / as the path separator.
