使用 import_module 从站点包访问模块

Question

I want to import all modules from a particular directory of a package which I installed using pip, that is, it lies in site-packages .

What I tried

Let's say the package name is package and it has a directory called directory . It has many files like a.py , b.py , etc. I need to import all of them. I listed all files in directory using in-built __file__ , which isn't the problem. When I tried to import the modules using importlib.import_module , I got ModuleNotFoundError even though I'm 100% percent sure they exist. I used relative import.

Code Snippet

modules is the list of all files in directory

for module in modules:
    importlib.import_module('.'+module, 'C:\\Users\\.....\\package\\directory')

ModuleNotFoundError: No module named 'C:\\Users\\.....\\package\\directory'

Finally

What am I doing wrong and what is the right approach to refer site-packages?

Answer 1

create an empty init .py file under the directory that you want Execute

import pkgutil
import sys


def load_all_modules_from_dir(dirname):
    for importer, package_name, _ in pkgutil.iter_modules([dirname]):
        full_package_name = '%s.%s' % (dirname, package_name)
        if full_package_name not in sys.modules:
            module = importer.find_module(package_name
                        ).load_module(full_package_name)
            print module


load_all_modules_from_dir('site-packages')
