TPool 1.3

Thread Pool for Python 2 and 3

It supports py2 and py3

Thread Pool for python 2 (and 3) with multiple parameters. Python2 include an undocumented thread pool which only accept functions with single arguments. TPool implements a pool for threads supporting multiple arguments

Install

pip install TPool

Why not PPool

If you want to have access to shared variables. But also note that in Python (at least the cPython version) include a global lock that it does not run multiple threads at the same time, but it is good enough if the bottle neck is disk IO or network.

Example

from TPool.TPool import Pool
from threading import Lock

pairs = []


def foo_merge(name, num, lock):
    global pairs
    lock.acquire()
    pairs.append((name, num))
    lock.release()


def example():
    global pairs
    pairs = []
    lock = Lock()
    local_pairs = [('A', 2), ('B', 3), ('C', 4), ('D', 5)]
    params = []
    for p in local_pairs:
        param = p + (lock,)
        params.append(param)
    pool = Pool(max_num_of_threads=3, func=foo_merge, params_list=params)
    pool.run()
    print pairs
