Python 3.5+inspectfunction

inspect.getcoroutinelocals()

coroutines and generators

A dict of the current local variables of a suspended coroutine, the async def counterpart of getgeneratorlocals.

Syntax

inspect.getcoroutinelocals(coroutine)

Until the coroutine has been advanced the dict holds only its arguments; body variables appear as it runs, and after it finishes the dict is empty. Useful in tests that drive a coroutine by hand with send(None), without an event loop. Pass the coroutine object, not the async function itself.

Examples

import inspect
class Pause:
    def __await__(self):
        yield
async def job(n):
    step = n * 2
    await Pause()
c = job(5)
print(inspect.getcoroutinelocals(c))  # → {'n': 5} — пока только аргументы
c.send(None)
print(inspect.getcoroutinelocals(c))  # → {'n': 5, 'step': 10}
c.close()
