import multiprocessing

def worker(lnk):
    ....    
def start_process():

if(PROCESS):
    pool = multiprocessing.Pool(processes=POOL_SIZE, initializer=start_process)

pool.map(worker, inputs)

如果你不介意执行别人的代码，这里是我的:

注意:有很多额外的代码你可能想要删除[添加是为了更好地说明和演示它是如何工作的]

注意:Python命名约定用于方法名和变量名，而不是camelCase。

工作过程:

MultiThread class will initiate with no of instances of threads by sharing lock, work queue, exit flag and results. SingleThread will be started by MultiThread once it creates all instances. We can add works using MultiThread (It will take care of locking). SingleThreads will process work queue using a lock in middle. Once your work is done, you can destroy all threads with shared boolean value. Here, work can be anything. It can automatically import (uncomment import line) and process module using given arguments. Results will be added to results and we can get using get_results

代码:

import threading
import queue


class SingleThread(threading.Thread):
    def __init__(self, name, work_queue, lock, exit_flag, results):
        threading.Thread.__init__(self)
        self.name = name
        self.work_queue = work_queue
        self.lock = lock
        self.exit_flag = exit_flag
        self.results = results

    def run(self):
        # print("Coming %s with parameters %s", self.name, self.exit_flag)
        while not self.exit_flag:
            # print(self.exit_flag)
            self.lock.acquire()
            if not self.work_queue.empty():
                work = self.work_queue.get()
                module, operation, args, kwargs = work.module, work.operation, work.args, work.kwargs
                self.lock.release()
                print("Processing : " + operation + " with parameters " + str(args) + " and " + str(kwargs) + " by " + self.name + "\n")
                # module = __import__(module_name)
                result = str(getattr(module, operation)(*args, **kwargs))
                print("Result : " + result + " for operation " + operation + " and input " + str(args) + " " + str(kwargs))
                self.results.append(result)
            else:
                self.lock.release()
        # process_work_queue(self.work_queue)

class MultiThread:
    def __init__(self, no_of_threads):
        self.exit_flag = bool_instance()
        self.queue_lock = threading.Lock()
        self.threads = []
        self.work_queue = queue.Queue()
        self.results = []
        for index in range(0, no_of_threads):
            thread = SingleThread("Thread" + str(index+1), self.work_queue, self.queue_lock, self.exit_flag, self.results)
            thread.start()
            self.threads.append(thread)

    def add_work(self, work):
        self.queue_lock.acquire()
        self.work_queue._put(work)
        self.queue_lock.release()

    def destroy(self):
        self.exit_flag.value = True
        for thread in self.threads:
            thread.join()

    def get_results(self):
        return self.results


class Work:
    def __init__(self, module, operation, args, kwargs={}):
        self.module = module
        self.operation = operation
        self.args = args
        self.kwargs = kwargs


class SimpleOperations:
    def sum(self, *args):
        return sum([int(arg) for arg in args])

    @staticmethod
    def mul(a, b, c=0):
        return int(a) * int(b) + int(c)


class bool_instance:
    def __init__(self, value=False):
        self.value = value

    def __setattr__(self, key, value):
        if key != "value":
            raise AttributeError("Only value can be set!")
        if not isinstance(value, bool):
            raise AttributeError("Only True/False can be set!")
        self.__dict__[key] = value
        # super.__setattr__(key, bool(value))

    def __bool__(self):
        return self.value

if __name__ == "__main__":
    multi_thread = MultiThread(5)
    multi_thread.add_work(Work(SimpleOperations(), "mul", [2, 3], {"c":4}))
    while True:
        data_input = input()
        if data_input == "":
            pass
        elif data_input == "break":
            break
        else:
            work = data_input.split()
            multi_thread.add_work(Work(SimpleOperations(), work[0], work[1:], {}))
    multi_thread.destroy()
    print(multi_thread.get_results())

是的，有一个线程池类似于多处理池，但是，它有些隐藏，没有适当的文档。您可以通过以下方式导入:-

from multiprocessing.pool import ThreadPool

我举个简单的例子

def test_multithread_stringio_read_csv(self):
        # see gh-11786
        max_row_range = 10000
        num_files = 100

        bytes_to_df = [
            '\n'.join(
                ['%d,%d,%d' % (i, i, i) for i in range(max_row_range)]
            ).encode() for j in range(num_files)]
        files = [BytesIO(b) for b in bytes_to_df]

        # read all files in many threads
        pool = ThreadPool(8)
        results = pool.map(self.read_csv, files)
        first_result = results[0]

        for result in results:
            tm.assert_frame_equal(first_result, result) 

是的，它似乎(或多或少)具有相同的API。

import multiprocessing

def worker(lnk):
    ....    
def start_process():
    .....
....

if(PROCESS):
    pool = multiprocessing.Pool(processes=POOL_SIZE, initializer=start_process)
else:
    pool = multiprocessing.pool.ThreadPool(processes=POOL_SIZE, 
                                           initializer=start_process)

pool.map(worker, inputs)
....

没有内置的基于线程的池。但是，使用queue类实现生产者/消费者队列可以非常快。

来自: https://docs.python.org/2/library/queue.html

from threading import Thread
from Queue import Queue
def worker():
    while True:
        item = q.get()
        do_work(item)
        q.task_done()

q = Queue()
for i in range(num_worker_threads):
     t = Thread(target=worker)
     t.daemon = True
     t.start()

for item in source():
    q.put(item)

q.join()       # block until all tasks are done

另一种方法是将进程添加到线程队列池中

import concurrent.futures
with concurrent.futures.ThreadPoolExecutor(max_workers=cpus) as executor:
    for i in range(10):
        a = executor.submit(arg1, arg2,....)
