stop-iter 0.2.4

An interuptable iterator for Python

stop_iter

stop_iter takes an iterable and returns a new iterable that can be safely stopped using SIGINT. This is useful when you have a long-running computation, such as machine learning training loops, that you want to be able to stop without losing all of the work that has been done so far.

Installation

pip install stop_iter

Usage

The following code will print the integers until you press Ctrl+C and then print "infinity".

from stop_iter import stop_iter

def integers():
  count = 0
  while True:
    yield (count := count + 1)

for n in stop_iter(integers()):
  print(n)

print("\ninfinity")
