python之线程

# 直接实例化创建
from threading import Thread

def sayhi(name):
    n=100
    for i in range(n):
        print('%s say hello%d
' % (name,i))

if __name__ == '__main__':
    t = Thread(target=sayhi, args=('egon',))
    t.start()
    print('主线程
')

 ===================================

# 直接实例化创建
# 继承Thread类创建方式
from threading import Thread

class Sayhi(Thread):
    def __init__(self, name):
        super().__init__()
        self.name = name

    def run(self):
        n=100
        for i in range(n):
            print('%s say hello %d
' % (self.name,i))

if __name__ == '__main__':
    t = Sayhi('egon')
    t.start()
    print('主线程')
