如何在Python中同时运行两个不同的代码？

import threading

def code1():
    # 第一个代码块
    pass

def code2():
    # 第二个代码块
    pass

# 创建线程
thread1 = threading.Thread(target=code1)
thread2 = threading.Thread(target=code2)

# 启动线程
thread1.start()
thread2.start()

# 等待线程结束
thread1.join()
thread2.join()

import multiprocessing

def code1():
    # 第一个代码块
    pass

def code2():
    # 第二个代码块
    pass

# 创建进程
process1 = multiprocessing.Process(target=code1)
process2 = multiprocessing.Process(target=code2)

# 启动进程
process1.start()
process2.start()

# 等待进程结束
process1.join()
process2.join()
