python threading怎么传参

在Python中，可以通过以下方式在线程中传递参数：

1. 使用threading.Thread对象的args参数来传递一个元组。例如：

import threading

def my_function(arg1, arg2):
    print(arg1, arg2)

my_thread = threading.Thread(target=my_function, args=("Hello", "World"))
my_thread.start()

2. 使用threading.Thread对象的kwargs参数来传递一个字典。例如：

import threading

def my_function(arg1, arg2):
    print(arg1, arg2)

my_thread = threading.Thread(target=my_function, kwargs={"arg1": "Hello", "arg2": "World"})
my_thread.start()

3. 继承threading.Thread并实现__init__方法来传递自定义参数。例如：

import threading

class MyThread(threading.Thread):
    def __init__(self, arg1, arg2):
        threading.Thread.__init__(self)
        self.arg1 = arg1
        self.arg2 = arg2

    def run(self):
        print(self.arg1, self.arg2)

my_thread = MyThread("Hello", "World")
my_thread.start()
