如何停止部分python程序的运行，而让其余的程序正常执行？

import threading
import time

# 定义线程执行函数
def thread_function(name):
    while True:
        if threading.current_thread().name == name:  # 判断当前线程名字是否需要停止
            print(f'Thread {name} is stopped.')
            break
        else:
            print(f'Thread {name} is running.')
            time.sleep(1)

# 创建并启动多个线程
thread1 = threading.Thread(target=thread_function, args=('Thread 1',))
thread2 = threading.Thread(target=thread_function, args=('Thread 2',))
thread1.start()
thread2.start()

# 停止线程1的运行
time.sleep(3)
thread1.join()  # 等待线程1结束

Thread Thread 1 is running.
Thread Thread 2 is running.
Thread Thread 1 is running.
Thread Thread 2 is running.
Thread Thread 1 is stopped.

import multiprocessing
import time

# 定义进程执行函数
def process_function(name, flag):
    while True:
        if flag.value == name:  # 判断共享内存中的值是否需要停止
            print(f'Process {name} is stopped.')
            break
        else:
            print(f'Process {name} is running.')
            time.sleep(1)

# 创建共享内存和进程
flag = multiprocessing.Value('i', 0)  # 共享内存，用于控制进程的运行
process1 = multiprocessing.Process(target=process_function, args=('Process 1', flag))
process2 = multiprocessing.Process(target=process_function, args=('Process 2', flag))
process1.start()
process2.start()

# 停止进程1的运行
time.sleep(3)
flag.value = 'Process 1'  # 设置共享内存的值，通知进程1停止运行
process1.join()  # 等待进程1结束

Process Process 1 is running.
Process Process 2 is running.
Process Process 1 is running.
Process Process 2 is running.
Process Process 1 is stopped.
