在线程中运行类方法(python) [英] Run Class methods in threads (python)

问题描述

我目前正在学习Python和类，我有一个基本问题，但没有找到任何答案.假设我有这个虚拟课程

I'm currently learning Python and Classes and I have a basic question, but I didn't find any answer to it. Let's say I have this dummy class

class DomainOperations:
    def __init__(self, domain):
        self.domain = domain
        self.domain_ip = ''
        self.website_thumbnail = ''

    def resolve_domain(self):
        #resolve domain to ipv4 and save to self.domain_ip

    def generate_website_thumbnail(self):
        #generate website thumbnail and save the url to self.website_thumbnail

我想同时运行resolve_domain和generate_website_thumbnail，当线程完成时，我想打印IP和缩略图.

I want to run simultaneously resolve_domain and generate_website_thumbnail and when the threads are finished I want to print the IP and the thumbnail.

编辑:我知道我应该使用线程，也许是这样的

I know I should use threads, maybe something like this

r = DomainOperations('google.com')

t1 = threading.Thread(target=r.resolve_domain)
t1.start()

t2 = threading.Thread(target=r.generate_website_thumbnail)
t2.start()

但是我应该在课堂之外使用它们吗?我应该编写另一个类来处理线程吗?

But should I use them outside the Class? Should I write another Class to handle Threads?

正确的方法是什么?

推荐答案

如果从类中调用它们，则非常简单:

If you call them from the class, it is as simple as:

import threading

class DomainOperations:

    def __init__(self):
        self.domain_ip = ''
        self.website_thumbnail = ''

    def resolve_domain(self):
        self.domain_ip = 'foo'

    def generate_website_thumbnail(self):
        self.website_thumbnail= 'bar'

    def run(self):
        t1 = threading.Thread(target=self.resolve_domain)
        t2 = threading.Thread(target=self.generate_website_thumbnail)
        t1.start()
        t2.start()
        t1.join()
        t2.join()
        print(self.domain_ip, self.website_thumbnail)

if __name__ == '__main__':
    d = DomainOperations()
    d.run()
