本文实例讲述了Python定时执行之Timer用法。分享给大家供大家参考。具体分析如下:
java中Timer的作用亦是如此。python中的线程提供了java线程功能的子集。
#!/usr/bin/env python from threading import Timer import time timer_interval=1 def delayrun(): print 'running' t=Timer(timer_interval,delayrun) t.start() while True: time.sleep(0.1) print 'main running'
t是一个Timer对象。【估计内部是使用一个线程】delay一秒钟之后执行delayrun函数。
其中time.sleep函数是用来让主线程暂停一点时间再继续执行。
希望本文所述对大家的Python程序设计有所帮助。

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.

When encountering a "commandnotfound" error, the following points should be checked: 1. Confirm that the script exists and the path is correct; 2. Check file permissions and use chmod to add execution permissions if necessary; 3. Make sure the script interpreter is installed and in PATH; 4. Verify that the shebang line at the beginning of the script is correct. Doing so can effectively solve the script operation problem and ensure the coding process is smooth.

Python lists can store different types of data. The example list contains integers, strings, floating point numbers, booleans, nested lists, and dictionaries. List flexibility is valuable in data processing and prototyping, but it needs to be used with caution to ensure the readability and maintainability of the code.
