For when your object graph is too big

.. code-block:: python

class A:
    def __init__(self, b: B):
        self.b = b

class B:
    pass

svc = {
    'a': A,
    'b': B,
}
context = Pytel(svc)
assert context.a.b == context.b

See usage <https://github.com/mattesilver/pytel/blob/master/tests/pytel/test_usage.py>_ for more cases

Features

• Build a graph of objects based on init methods or factory functions
• Initialize from
  • a dictionary of string to any of:
    • callable
    • type
    • value
  • Object containing any of:
    • object fields with objects or types (or callables)
    • class fields with objects or types (or callables)
    • methods
    • static methods
  • An Iterable of the above
• Verify integrity of the dependency graph using type annotations
• Recurrently resolve all dependencies at the first reference
• Works as a Context Manager, on exit close all objects that are Context Managers

Because of strict type checking this package is probably quite unpythonic.
