Python 3.2+inspectfunction

inspect.getgeneratorstate()

coroutines and generators

A generator's state as a string: GEN_CREATED, GEN_RUNNING, GEN_SUSPENDED or GEN_CLOSED.

Syntax

inspect.getgeneratorstate(generator)

States are plain strings, available as the inspect.GEN_* constants; compare against those. GEN_RUNNING is visible only from inside the generator itself. An exhausted generator and one closed with close() are both GEN_CLOSED, while a created but not started one is GEN_CREATED and accepts only send(None). Coroutines have their own getcoroutinestate.

Examples

import inspect
def g():
    yield inspect.getgeneratorstate(gen)
gen = g()
print(inspect.getgeneratorstate(gen))  # → GEN_CREATED
print(next(gen))  # → GEN_RUNNING
print(inspect.getgeneratorstate(gen) == inspect.GEN_SUSPENDED)  # → True
gen.close()
print(inspect.getgeneratorstate(gen))  # → GEN_CLOSED
