threading.Thread传参列表
时间: 2023-08-24 22:06:05 浏览: 31
可以通过args参数传递一个包含多个参数的列表,示例代码如下:
```python
import threading
def func(a, b, c):
print(a, b, c)
args = [1, 2, 3]
t = threading.Thread(target=func, args=args)
t.start()
```
在上述代码中,传递了一个包含三个参数的列表args给Thread对象,然后在func函数中通过解包来获取这些参数。注意,args参数必须是一个元组或列表类型,如果只有一个参数,需要在参数后面加上逗号,否则会被认为是一个单独的值而不是一个元组。

python threading.Thread 传参
在Python中使用threading模块创建线程时,可以使用threading.Thread类的构造函数来传递参数。具体方法是在创建threading.Thread实例时,将需要传递的参数作为关键字参数传入构造函数中。例如:
```python
import threading
def my_function(arg1, arg2):
# do something with arg1 and arg2
print(arg1, arg2)
thread = threading.Thread(target=my_function, kwargs={'arg1': 'hello', 'arg2': 'world'})
thread.start()
```
在上面的代码中,我们将arg1和arg2作为关键字参数传递给了threading.Thread构造函数,这样在调用线程的start()方法时,就可以将这些参数传递给my_function函数。\[1\]

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()
```
