Tools to inspect python objects
To install: pip install tec
modules_imported
is a generator of module names from obj.
It uses string parsing, so is not as accurate as some other methods, but is fast and flexible,
and doesn't require actually running any of the code analyzed.
>>> from tec import modules_imported
>>> import os.path # single module
>>> list(modules_imported(os.path)) # list of names in the order they were found
['os', 'sys', 'stat', 'genericpath', 'genericpath', 'pwd', 'pwd', 're', 're']
>>> import os # package with several modules
>>> from collections import Counter
>>> Counter(modules_imported(os, only_base_name=True)).most_common() #doctest: +ELLIPSIS
[('nt', 5), ('posix', 4), ... ('warnings', 1), ('subprocess', 1)]
>>> from tec import modules
>>> sorted(modules.second_party_names(modules))[:5]
['DOTPATH', 'FILEPATH', 'FOLDERPATH', 'LOADED', 'ModuleSpecKind']
>>> sorted(modules.second_party_names(modules, callable))[:4]
['ModuleSpecKind', 'coerce_module_spec', 'filepath_to_dotpath', 'finding_objects_of_module_with_given_methods']
>>> sorted(modules.second_party_names(modules, lambda obj: isinstance(obj, type)))
['ModuleSpecKind']
A few functions to investigate what objects can be imported from a module (and the depth of the dot-path to import those objects directly).
The main function, print_top_level_diagnosis
,
prints a diagnosis of the imports that can be optained from the (top level) module.
That is, those objects that can by imported by doing:
from module import obj
though the object's code may be several package levels down (say module.sub1.sub2.obj).
