本文实例讲述了python任务调度实现方法。分享给大家供大家参考。具体如下:
方法1:
import sched, time import os s = sched.scheduler(time.time, time.sleep) #scheduler的两个参数用法复杂,可以不做任何更改 def playmusic(x): os.system(x) def jobtodo(): tmlist = [2011,8,11,22,15,0,0,0,0] x1=time.mktime(tmlist) x2=time.time() y=x1-x2 #计算任务到现在的时间长度 s.enter(y, 1, playmusic, ('mplayer /home/c.mp3',)) #四个参数分别为:间隔事件、优先级(用于同时间到达的两个事件同时执行时定序)、被调用触发的函数,给他 #的参数(注意:一定要以tuple给如,如果只有一个参数就(xx,)) s.run() print time.time() jobtodo()
方法2:
import os import time from threading import Timer def playmusic(x): os.system(x) def jobtodo(): tmlist = [2011,8,11,22,40,0,0,0,0] x1=time.mktime(tmlist) x2=time.time() y=x1-x2 Timer(y, playmusic, ('mplayer /home/b.mp3',)).start() jobtodo()
希望本文所述对大家的Python程序设计有所帮助。

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
