问题

我试图在两个不同的多进程线程中的两个函数内使用一个变量，但似乎该变量无法共享...

```python
import multiprocessing

threads = []
counter = 0

def my_function():
    global counter
    while True:
        counter += 1

def my_function_two():
    global counter
    while True:
        print(counter)


threads.append(multiprocessing.Process(target=my_function))
threads.append(multiprocessing.Process(target=my_function_two))

for j in threads:
    j.start()

for j in threads:
    j.join()

我看到了关于在线程中共享全局变量的不同问题，但它们都没有帮助。

提前感谢

I&#39;m trying to use a variable inside two functions in two different multiprocessing threads, but it seems that the variable can&#39;t be shared...

import multiprocessing

threads = []
counter = 0

def my_function():
global counter
while True:
counter += 1

def my_function_two():
global counter
while True:
print(counter)

threads.append(multiprocessing.Process(target=my_function))
threads.append(multiprocessing.Process(target=my_function_two))

for j in threads:
j.start()

for j in threads:
j.join()

I saw different questions about sharing global variables in threads but none of them are helpful.

Thanks in advance

这是我的代码

```python
import threading

threads = []
counter = 0

def my_function():
    global counter
    while True:
        counter += 1

def my_function_two():
    global counter
    while True:
        print(counter)

threads.append(threading.Thread(target=my_function))
threads.append(threading.Thread(target=my_function_two))

for j in threads:
    j.start()

for j in threads:
    j.join()

import threading

threads = []
counter = 0

def my_function():
    global counter
    while True:
        counter += 1

def my_function_two():
    global counter
    while True:
        print(counter)


threads.append(threading.Thread(target=my_function))
threads.append(threading.Thread(target=my_function_two))

for j in threads:
    j.start()

for j in threads:
    j.join()
