Wrapper on an iterable to support interruption & auto resume, retrying and multiprocessing.
The code is tested on Linux.
APIs
Please refer to the signature of function.iterate_wrapper or generator.IterateWrapper for usage.
Examples
iterate_wrapper
from typing import IO
from time import sleep
from iterwrap import iterate_wrapper
def square(f_io: IO, item: int, fn: Callable[[float], float]):
result = fn(item)
f_io.write(f"{result}\n")
data = list(range(10))
num_workers = 3
iterate_wrapper(
square,
data,
output="output.txt",
num_workers=num_workers,
fn=lambda x: x * x,
)
with open("output.txt") as f:
print(f.read()) # [0, 1, 4, 9, ..., 81]
IterateWrapper
Just the same as tqdm.tqdm.
from iterwrap import IterateWrapper
data = [1, 2, 3]
results = []
for i in IterateWrapper(data):
results.append(i * i)
print(results) # [1, 4, 9]
