该模块定义了一个注册清除功能的功能,如此注册的功能在正常的解释器终止时自动执行.
[root@centos3 liujiangbu]# vim 2.py
file = open('test.txt','a')
def goodbye(name, adjective):
print('Goodbye, %s, it was %s to meet you.' % (name, adjective))
import atexit
t = input("qingshurunidemingzi:")
q = input("qingshushurnfsdff:")
file.write(q)
file.close()
atexit.register(goodbye, adjective='nice', name='Donny')
print(file)
def test(q):
print(q)
test(q)
print(6666)
执行结果：
[root@centos3 liujiangbu]# python3 2.py
qingshurunidemingzi:ddd
qingshushurnfsdff:ddd
<_io.TextIOWrapper name='test.txt' mode='a' encoding='UTF-8'>
ddd
6666
Goodbye, Donny, it was nice to meet you.
可以看到atexit.register(goodbye, adjective='nice', name='Donny')调用的函数最后被执行
