Tools to inspect python objects

To install: pip install tec

Examples

Generator of module attribute names that point to object the module actually defines.

Modules

>>> 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']

Packages

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).

Peek

>>> from tec.peek import print_signature
>>> print_signature(print_signature)
func
sep: Union[str, NoneType] = '\\n'
prefix: str = ''
suffix: str = ''
>>> print_signature(print_signature, None)
(func, sep: Union[str, NoneType] = '\\n', prefix: str = '', suffix: str = '')
>>> print_signature(print_signature, '\\n * ', prefix=' * ', suffix='\\n')
 * func
 * sep: Union[str, NoneType] = '\\n'
 * prefix: str = ''
 * suffix: str = ''
