a RG5dBã@sdZddlmZdgZdS)aè Unified place for determining if external dependencies are installed or not. You should import all external modules using the import_module() function. For example >>> from sympy.external import import_module >>> numpy = import_module('numpy') If the resulting library is not installed, or if the installed version is less than a given minimum version, the function will return None. Otherwise, it will return the library. See the docstring of import_module() for more information. é)Ú import_modulerN)Ú__doc__Zsympy.external.importtoolsrÚ__all__©rrúS/var/www/html/django/DPS/env/lib/python3.9/site-packages/sympy/external/__init__.pyÚs
